Why do i feel guilty about calling the police on my dad and sending him to jail?

[Slakker Mahn]

You did the right thing. In life, you get the behaviour you tolerate, and your dad's behaviour has not changed because it's what your mother tolerated.

That's not to say he'll change as leopards rarely change their spots, but at least he may curb it as he'll know that it's unacceptable and there's consequences.

But with "red zone" behaviour, it can't wait until the person is out of control... at that point the logic and rational of having the police come may not stop him... need to de-escalate before it gets to that point.
