And what is also insane,

is that whatever is that absolutely not permissible to himself,
he does it to other people.  Verbally attacking behind the person's back.
If to retaliate or defend verbally, that is met with violence/threat.

And when they retaliate at the same level,
while he is the one who initiates it,
he escalates it  to the point of life and death.

Or terrifies the environment so it doesn't even begin.

I do believe that he is somewhat tortured person,
and has a kind of "death wish" despite all the hopes he state.

He can throw away his life for the sake of 'winning' in that moment.

To deal with someone psychologically dangerous, who gambles in all things he does.
Regardless of the outcome, toward himself or others, by bravado.

He don't belong in society.

He poses serious risk to himself, and other people.

Because he CREATES dangers.

Think about this.

It's he who creates it. Where does it come from?
