In real life luis is what we like to call "thugs." He has no grief, he is a hoodlum and should go back to juveinile hall. I think because he is selfish. I say he selfish because he cares about what happen to his mom. He didn't feel bad when he broke into that old ladies home. To me rthat is just awful. What if that ladie woke up and saw him and had a heart attack. Maybe he had a little grief, but a little is nothing.
