>>12041853his dad wasn't around. probably had less strict upbringing and when his dad was around, he probably tried to enforce his rules despite having not enough work put in.
he put food on the kids table but he also may have cheated alot with many women, and that is the catalyst for their christmas fight.
what happened is that he didn't 'drink himself to death' they both quit drinking together and he ended up having a seizure and dying. you can die if you quit cold turkey and have been abusing it. that's how amy winehouse died.
