Marty.
Am I the only one who feels bad for Marty? He was portrayed like a nutcase in this movie when he was really a troubled guy with an alcohol problem. Even his own sister Madonna said "Don't leave me alone with him" and "My brother's crazy". Chris also had that same arrogant attitude, looking down on his brother. I guess that whole "Keep It Together" song was written in good fun. What a nice family
