Huh, I actually agree with ya.
I've more interpret it like "don't go full eye for eye, teeth for teeth" or whatever the English expression is.
So basically respect your enemies, appreciate them how they are, and get what you can learn from them. So just a pure passific with no hate or whatsoever.
I also like the Toriel way : "If you enter in a FIGHT, strike with a friendly conversation".
Last thing, enemies doesn't always mean the people who WANT to hurt you. Enemies can be in one way, yours. And that can be really bad.
But yeah don't be f**king naive, loving your enemies doesn't mean jumping in a trap. (I don't think Jesus was naive, he knew what he was doing)
