What if you don't feel remorse for cheating on a HS boyfriend, how bad is that?

We're both 16 year-olds and so is the other guy. I got caught making-out and both guys still had a brief fight. I must admit, seeing them fighting was hilarious. The fight was even, neither won. I tried to keep a straight face but kept giggling.

I mean yeah it was wrong, it was bad but I don't really feel actual remorse and never been in a position where I'm asking for forgiveness. I guess it's over now. The other guy doesn't want me either. Still, I feel disconnected from all this. Is this normal? How bad is it to really don't feel remorse for cheating on my HS boyfriend? We only dated for just 6 months anyways.

Background:

My own parents cheated on each other and I saw all that drama during my younger years. My father cheated first; he cheated with 3 women (2 ONS and 1 long-term affair) and my mother got revenge on him. She cheated with one of his co-worker. She felt no remorse for that revenge. They're pretty much like roommates. There is no love there so whatever. It's not too much of a marriage. I don't get involved in their business anyway.
