This guy doesn't even care about being a great fighter. He said it himself.
"I want to be the hardest person on earth. I want to be hard"
That isn't what a dominant martial artist says or wants. Being hard is for fucking idiots who think they're big and strong and then get their asses kicked by anyone with minimal training. The only thing "hard" about Till are his emotions towards his family that he apparently doesn't care about much.
Young fathers who don't give a damn about their kids are among the worst people. Straight up.
