The way you are SUPPOSED to do it though is to get all of your alignment to JOIN YOU in fighting a war against the others. Then any unit that they lose IN YOUR CAUSE, comes back and fights under your more competent leadership.
I've tried that, mostly they just have a few border skirmishes and then sit inside their own borders content with whatever you bribed them to go to war with. The worst case I had was with two continents, one full of good civs, the other evil - over two hundred turns of everyone at war and I as Basium was the only trying to killing anything. However my really small army was getting nowhere, so I came back to the other continent and wrecked havoc - ended up with a huge number of angels and cities, and went on to conquer the map.
Surely Basium should be penalised for attacking good civs, not given angels from those he kills.
