re: If you were sentenced for a crime and already served can they resentence you to more time

It just seems very odd to me that if the intent is the same why is one outcome punished much more harshly.

I'm not defending drunk driving but the "she should get much more than x years" just seems quite odd to me when the intent is the same.

From a moral perspective, both actions are the same, i.e. all drunk driving is bad.

From a legal perspective, we have very disparate punishments for essentially the same action.
