How much of a douche is my friend?

[Rev. Good Will]

EDIT- Fudge, I realize we have the dorm for this type of thing now, mod move please. My mistake

And is it even worth getting involved?

Cliff notes: One of my friends "Sam" is over his head in college; both financially, and academically. He used to dorm, now will commute. Another one of my friends "Jacob" commutes to this school and refuses to give him a ride to class as a way of tough love, and trying to get him to go to another school.

So my High School friend Sam previously went to a community college, and got by with very marginal grades. The rest of my HS friends all went to a private school, and are doing fairly well. Sam wants to go hang out with all his friends from high school. Everyone thinks Sam shouldn't do this due to all the loans he will need, as well as the courseload is significantly harder in this school. Sam dorms, rooms with a friend from HS, and for a symester drinks, smokes pot, plays World of Warcraft, and fails 3 classes out of 5. Facing more schooling to catch up, and therefor more loans, Sam deiceds to commute, but the problem is he doesn't have a car or a lisense. To get to school, Sam must now take the bus, or ask a friend of ours who also goes to the same school to give him a ride, Jacob. Jacob doesn't want to give Sam a ride for numerous reasons: 1 - Sam take [censored] forever to get ready, and would slow Jacob down. 2 - Jacob uses the commute drive as personal reflection. 3 - Jacob refuses also as a method to prevent Sam from coming to the school, as a "tough love" of sorts.

I, although disagree with what Sam is doing entirely, think Sam will continue to go down this path, and be making these mistakes. I however don't think it is Jacob's place to make this decision for Sam, as he has to realize it on his own, and also shouldn't treat Sam like a child (though Sam acts like one alot).

I am trying to convince Jacob to at least agree to he tells Sam his schedule, and what time he plans on leaving. If Sam happens to be at his house before/at this time, then give the kid a ride. Jacob is refusing.

Who is more in the wrong? Any more thoughts on this?
