It's probably not as bad as finding out about the Balldo or as damaging as being a degenerate drunk around the family, but it's somehow more distasteful to me than a lot of the other bad role model aspects of his life.
If his children rebel and stand against him, it will be painful for them. But ultimately, it will mean that their scarred souls can start healing.
However, the alternative scenario has to be always considered: Nicks' kids may go through life thinking their father is super normal and everyone else is weird. And then, they will have their own kids and raise them in a similar way. If Nick would tell them - hey, I am a degenerate and I'll never change, but what I am doing is wrong, and I want you to be better than me - we could remain optimistic. But he just doesn't strike me as a person who can genuinely, honestly self-reflect and admit to wrongdoings.
There were occasions where he was saying something self-critical, but to me, it always felt like baiting. Like when a girl posts "OMG am so ugly", just to get "Noooooo queen ur so pretty" comments back. Or even more manipulative - as to have an explanation for others - and peace of mind for himself - that he akshually is very very humble. He said it, so it must be true.
Is he humble though? Is a man screaming at one streamer, because another streamer is critical of him and won't be brainwashed, humble?
Is a man mocking somebody's mental health struggles, and painting himself as the Saviour and Good Samaritan, WHILST mocking, humble?
Is a man laughing about needlessly drowning a skunk TWICE, humble?
Have you ever worked with a person who would try to maintain the image of being very rational, professional and open to criticism, but as soon as you do politely criticise them, they would either blow up or start a passive-agressive war, and never EVER lose that grudge against you? That's my impression of Nick.
I don't think he can change, there is something wrong with his brain. Alcohol and financial success exacerbated it, but it was always there. Like a rotten seed waiting to grow into a rotten tree.
So yeah, it's gonna be a big gamba of life as to whether his kids wake up, or are they irretrievably lost in hands of this demonic man.
