No. There are too many variables at every scale of comparison to safely assume the level of competition any given student faced in each of their classes. It's not even fair to assume all classes within a single institution were curved, or curved in the same way.
Should students from schools that actively grade deflate get some slack? Sure, as long as their GPA is still competitive relative to that school's average. And if you read any of the five million previous threads on this topic, you will probably come across posts by AdCom members like LizzyM and Goro confirming that they already do this.
+1 I agree. There are just too many variables accross institutions, majors, classes, professors to even begin to try to objectively compare. To assign extra points to a school just because someone 'feels' like it's a better school than another (based on no truly objective measure) is really not fair at all. Not to mention that people go to different schools for different reasons.
In the end, the student made the choice to attend the school they did, and that choice should have been based on whichever school they thought they would do best at. You ("you" in general, not just you OP) made the decision to attend and stay at that school and it is ultimately up to you to deal with that decision.
