Well, I don't 'hate', but I will dislike and disrespect a person based upon who they are as a human being by their own choices. I do fully comprehend your opinion, however...I respectively disagree. I consider myself a very complex individual too in many ways, and my own childhood was one of which likely was very comparible to LJ's, if not worse.
I may be judgmental on the subject, but considering my own very bad & abusive childhood, and my not allowing it to be an excuse/reason for my adult failures/success' in life...I haven't much empathy for the 'blame it on the childhood' excuse.
There are many times in my life I have to bite my tongue, not react 'naturally'...it takes inner strength to maintain self control and self discipline. Sometimes yes...we lose it naturally as humans...but, we hopefully are mature enough to learn from those mistakes, build upon our inner strength of learning self control & discipline...and not keep repeating such disasterous mistakes. LJ doesn't appear to have that aspect of inner strength, nor of which he can learn from past mistakes of losing self control & build his inner strength to resist temptation...and he's proven it repeatedly.
It's one thing to make a mistake, it's something else to keep on making the same ones...and LJ does, he never learns from his mistakes, and goes about his life not honestly accepting accountability for his own mistakes. If as you say, his behavior is beyond his control...then obviously he needs professional help with learning self discipline and how to build inner strength to resist anger & temper issues.
His lack of such likely will ruin his life in the long run, and very possibly his career in the NFL if he doesn't soon get his irresponsible, immature, unprofessional, and emotionally/physically abusive mentality together. He wants a pro's salary...to live a posh lifestyle, then he needs to earn it professionally in all aspects...including his mentality.
Respectively speaking...it does appear IMO that you are making excuses for him, and there honestly are none.
And everyone in agreement say Amen
