If you looked into the heart of your enemy

People I consider enemies I don't care to look close enough to see anything about them

I couldn't answer that unless I had an idea where my enemy is from, their ideology, and end game. If it's to attempt to conquer and subdue my country my sense is that I might not find one.
That said, there's a whole litany of separate discussions on the who's and why's.

I try not to humanise ppl I hate.. I’d end up liking them 😇

Intriguing question...

I think fear.
