@oralloy,
That’s not self defense, in any sane person’s estimation. That was the expression of an emotionally unwell person.
Whether she called you an idiot, or a coward, or a ridiculous, delusional liar and fool…
To retaliate by wishing her pet’s death caused her pain was like blinding someone for looking at you hard.
It was something that a weak, weak-minded person would do. Someone not fit to be in decent company. Someone that needs to be medicated and/or isolated.
