I agree with you, but, I repeat, we're humans. We're very slow at learning. Following your logic there would be no more wars because we would get that they don't bring us any good. And wars today are as bloody as they ever were.
Weapons may be more deadly, but war overall is fought on a much smaller scale. Insurgencies, and proxy wars are on the trend. The last really large war was WW2, and WMDs have made that happening again unlikely.
