I dunno, Chuck. Just think of the most heinous act you can. Imagine your child doing it. Repeatedly. Maybe even to you. Can you really still say you love your child? If you do, then I have no idea what love means. Which is quite possible.
I have two wonderful children, and I love them more than life. But if they were to change, and become completely evil, I’d feel horribly guilty, and probably want to kill myself.
There can come a time when parents disown children. I’m not sure how it happens, but I imagine when enough ill will has passed between parents and children, the relationship can be severed.
Let’s just say your notion of love and mine are different, and leave it at that, shall we?
