Not sure I agree. 25 years in prison is life-ruining. Even if he ultimately gets out in 10 (or whatever), his life will be forever changed for the worse because of this, even with rich parents who will get him back on his feet after he's out.

I think the kind of person who would see this sentence and think "eh, no big deal if that happens to me" would probably still not be fazed if he got a significantly longer sentence.
