Maybe so, but so what? A person is born weak and gets picked on and this gives him the drive to be big and strong. A person is born into poverty and this gives him the drive to be a financial success. Arnold has always admitted that he wasn't normal and this need to be notices and famous "to be remembered like Christ."
Often it is the imbalance ones that make a differenc in the world. What normal person would want to be President?
Sherman didn't torch Georgia and bring the Civil War to an end because he was just your normal everyday bloke.
A person basically spends his whole life hating himself for not being something he would like to be, or someone his parents would like him to be, and everything he does revolves around things he hopes will make him Better in his own eye or in the eye of someone's else that is very important to him. Problem is nobody really gives a shit about him and what he does, that's the illusion.
For some it results in good things hapening like you said it, to most it results in abnormal, extremistic and destructive behaviors that go nowhere.
It's all about how you balance all these things of course, but obviously destroying your body and your health when you know you're at risk cannot be described as a positive behavior, especially when you have loved ones surrounding you. If you are so obnoxious that you are killing yourself while being surrounded by people who are important to you, then you have mental issues/traumas, or these people simply dont mean shit to you.
If kris dim does what he does, endangering his health just because he does it for himself and for nooneelse/ no other subconscient reason,if he had no family then it would be understandable. It would be the "fuck all " attitude that is so promoted in our moden superficial world.
But taking into consideration he actually HAS A FAMILY, it means that in his personal view of the world, being more muscular is more important to live a long life with your loved ones.
This is not a sane, and normal way to think.
