I thought about the issue of a DUI being seen as less severe than a cheating IA and this is what I came up with as an impartial third party after seeing both sides of the argument. and here is what I have come up with:
Assuming OP commits a DUI and cheating and is not caught in either scenario, the DUI doesn't give OP something they did not deserve. In the case of cheating, if OP has been cheating before, that means they did not deserve their current 3.9, GPA which could start a domino effect and lead OP to obtain other things they did not deserve: scholarships, admissions to medical school, etc. Also, a DUI is also severely punished: a fine, jail time, etc. A cheating IA is not. All you get is an annotation on your transcript and some universities delete these IAs from their records and the student's transcript after a set amount of years and if the cheater requested their letter writers not to mention it on their LORs after it has been deleted from OP's file, they're basically a clean student and adcoms will never be the wiser.
Here, I will talk about how obvious it is and in regards to work and for the purposes of proving my point, I will use OP's Freudian slip, which suggests OP would have continued to cheat if they weren't caught. You also can't show up to work in a hospital drunk or in a hangover. Even if OP DUI'd without being caught and made it to work, it will get noticed immediately and they can send you home and discipline you and no harm will be done from you coming into work drunk. If OP retains their cheating habits as a physician and provide substandard care, resulting in a patient dying, it can be covered up as a "medical error" because we're all human, we are bound to make mistakes from time to time. If OP is sued, let's cover both cases: if OP wins the malpractice suit and loses. Let's talk about winning first. If OP wins, they may be on edge for a while but because old habits die hard, they can slip back to providing substandard care just to make things easier on themselves. Let's talk about losing the lawsuit now. In civil cases, only money is involved. OP will not serve jail time and the insurance company will cover the settlement. Also, honest medical errors are common since a physician is tiresome work and it is the third leading cause of death in the US. So it would be hard to conclude OP purposely provided substandard care so they could go home early or whatever. According to the link, even if OP lost a suit, they would not lose their license immediately, but they can be subject to an investigation if they had a certain number of suits within a certain period of time. So OP would be on edge for a year or two, then slip back into their cheating ways and provide substandard care, which could eventually result in another unnecessary death. Even if OP lost that suit, sufficient time will have passed and it would be hard to say for sure OP purposely provided substandard care. As long as OP avoids having 2+ lawsuits within a certain period of time, if they get sued and that time period has elapsed, they would go back to providing substandard are until a patient dies under them again. Now let's talk about what would happen if OP lost their license, this means the adcoms responsible for admitting OP into medical school made a poor decision admitting someone like OP when the seat could have gone to someone who would have a medical career and be able to help more people until their retirement.
In every case I tried to apply a DUI and cheating to, a DUI is more upfront and less deceptive than a cheating IA.
However, if on their IA essay, OP acknowledged taking shortcuts by cheating will provide OP with substandard knowledge and would compromise their ability to provide adequate care for their patients, I would give them fair consideration because everyone makes stupid decisions. Being under 25, I can understand if you make stupid decisions because our brains develop from back to front. That means your prefrontal cortex (I am assuming you're not 25) is still developing when you were caught, so in this respect, it's not your fault our brains are evolutionarily wired to develop from back to front. It's evolution's fault. I can guarantee you there is not one person that made a stupid decision without thinking it through because their prefrontal cortex is slow to develop. Notice I am not calling your cheating a mistake because it was not a mistake. You knew about the consequences but failed to think it through.
Disclaimer: some of my input came from this link.

If I am going to be honest, if, in theory, I was OP's peer mentor and OP told me they have a track record of cheating without being caught, I would not immediately turn them in. The reason why is being able to cheat repeatedly shows OP is extremely diligent and I would try to enlighten OP by taking them to a hospital to show them just how serious healthcare is and if they provided substandard care, people could die under OP's care. This way, I can get OP to focus their diligence onto something positive: paying closer to their patient's charts and history and providing excellent patient care and possibly saving lives by noticing small details most people would miss, including other physicians. I got this idea from Vin Diesel. When he was a kid, he and some friends broke into a theater to vandalize it, but they were caught. Rather than report them to the police, the theater manager gave them roles in the theater to focus their time and energy onto something good and keep them off the streets. That's how Vin Diesel's acting career got started. Given how he turned out, I say the manager made the right call. Likewise, I would try to get OP to realize the error of their way and focus that diligence into being honest and for the benefit of others as a physician rather than for himself. If OP still continued to pursue medicine and cheat, then I would report OP because honestly, you would have to be a horrible human being to continue cheating after being shown what could happen if you take shortcuts in providing patient care and still continue to do it. If someone could give me their input on this theoretical scenario and tell me if they agree or disagree with me and why, it would be appreciated. I like to see both sides' argument on issues or scenarios like this.
