> Most people don't see themselves as destructive, they just have a very different view of what the right rules are and what ought to be done to progress things. That can appear destructive from the outside.

I think that's partly true. e.g. pro life vs pro choice I can see both sides pushing for what they think is right.

Some people though do bad things, knowing those things are bad. But they do it anyways because it benefits them. So maybe it's not seeing themselves as being "destructive" per se, but at least not caring about the negative consequences to others.
