1. Rape is bad, and I think most rational people will agree.
2. War, since it affects more people, is worse. My opinion, I suppose, but I think a majority would agree.
3. Hardcore porn perhaps has been a factor in rape. However, I don't believe I've heard of HC porn being a cause of war. At least not a large nor somewhat recent war.
4. Religion has been a cause of war. Now it can be claimed that your religious side of the war is the 'good' side of the war. But since often both sides claim that their religious side of the war is the 'good' side of the war, you'd have to agree that 50% of the religious war is not the 'good' side. And could go to 100% if you think both sides are 'bad'.
Thus, in terms of how bad something is (or can be bad, especially if only its downside nature is looked at) in relativeness of being bad, going from least bad to worse bad.
