Please, stop trying to blame any person, place, or thing for choices Lamar Odom made himself.
Drug and alcohol addiction is a disease. The problem has been out now for a long time.
Odom's father probably had the most power, in the way of influence, to help Lamar overcome his addictions if he had been able to overcome his own.
You live what you know by what you've learned. Genetics play a large part too.
From what I've seen on the TV show, Khloe loves Lamar and tried to deal with and help him. She had no choice other than to let him go due to his addictions. It appeared, in the latest show, she was still struggling to do so too. Trying to rescue an addict is like repeatedly hitting your head against a wall. As you watch a person you love spiral downward, the heartbreak becomes too much. Those same sweet people often become abusive if you get in their way or question them about their destructive habits. For this reason, Kim wanted to see Khloe break free emotionally from Lamar. Kim is right, not mean, unfeeling or selfish.
Scott Disick would be wise to seek help now.
People can live sober lives and be happy.
