I remember being extremely spiteful when I first got attacked in Civ.

I didn't just wipe them off the map; I first found a tiny one tile island near one of the poles with a couple of resources around. I then forced them to take ownership of the island in a war and then in subsequent wars took all of their other cities.

I then spent the remainder of the game leaving 2 privateer units (the only unit which can pillage unprovoked) destroying any fishing boats which left their now-capital. Every so often I would just gift them technology knowing that their capital wouldn't be able to make use of it. This happened for over 700 years before the game ended.

In other words, I kept a civilization around just to punish them for a minor transgression of their ancestors. I like to believe I am a kind and compassionate person...
