There is nothing twisted about doing the right thing. Nowadays peeps will justify and rationalize anything.
Ha! My mother made this rationalization when getting hired as a nurse in 1953 while my dad was in the Navy. The hospital was near a naval base and, as predicted, my mom was trained in a specific unit and then left after my father was discharged from the service. It's nothing new.
OP is applying for a forensic assistant position that will require, I surmise, extensive training to collect and safeguard evidence in a crime. The evidence will be used by prosecutors to put people in prison, taking away their freedom.
Consider the consequences...
One of my sibs worked for awhile in a medical examiner's office. The job included fetching bodies from the scene, driving them to the morgue for autopsy, and doing the lugging and heavy lifting. At the time, the kid had a HS diploma and had worked awhile as an orderly and a morgue attendant in a hospital.
The situations he faced were not always crime investigations but included vehicle crashes (motorcycles, cars, small planes) drownings, drug overdoses, house fires, exposure. He learned by doing. If it was a crime scene, the police would be there and would release the body to him after they'd gathered their evidence.
In most employment situations, the employee is not under contract and can be let go at any time without cause. Likewise, the employee can walk at any time, generally with a couple weeks notice. Should the employer be obligated to disclose that funding is precarious and the gov't budget might be slashed resulting in layoffs next August? do you think that most employers would, or would not?
If this applicant already had an offer of admission and was slated to matriculate in August 2018, it would be fair to expect him to say so in an interview. However, given the long shot of being admitted in this cycle, the job candidate IMO can safely keep to himself that he's hoping to go to med school next year (or be selected to play a role on Broadway or win the lottery and move to Tahiti).
