Welcome to the world of antisocial personality disorders. The rationale goes:

That didn't happen.

And if it did, it wasn't that bad.

And if it was, that's not a big deal.

And if it is, that's not my fault.

And if it was, I didn't mean it.

And if I did, you deserved it.

It's called the "narcissist's prayer", it's what narcissists and sociopaths tell themselves to absolve themselves of accountability. Whatever the situation, they have an excuse as to how it's not their fault. It's like the stages of grief but for people trying to avoid consequences or guilt for their actions.
