Why are some people despicably inhumane and brutal?

Question

I just came up with this idea after having watched the videos called bumfights... I've found Dr Phil's refusal to interviewing this guest:

I personally have no hatred against any human being, indeed any single one. But why do some people hate certain group of people and abuse their human dignity? Where on earth does the evil mind come from?

I am very scared. Yes, I am sure there are more people who are generous and decent than the distracted ones. But, anyhow I am living in the same world where those number of risky people and disasters keep occurring, and thus I feel insecure with this unstable world.

And I feel so compassionate about the innocent and poor victims who had to be tortured by those sadistic wrongdoers. It is such a pity that the victims (homeless people, little kids, battered women, etc) are totally isolated from the protective institutions and supportive organizations..

Answer 1

Because good exists. That's why. The world needs violent or evil to co-exist with good. It's not logical I know, but think about it. If we lived in a place of pure and good* we wouldn't be dealing with death. If we lived in a world full of evil you wouldn't have seen compasionate good citizens balancing the earth with gracefull deeds. Such immorality in people with violence can also contribute to society as a whole. Look at the media, television or video games. You can't say violent material there does not influence other people into turning themselves as a copycat. Humans mimic a lot of what they see. Along with others I will not discuss because then I'll write more than I wanted.

Answer 2

unhappiness with oneself. Thats where the evil mind comes from. Some people are just predators looking for some prey to make themselves feel better or more powerful.

Answer 3

We live in a sinful world. Saten loves to watch the results of sin. He and his followers spend a lot of time and effort getting man to be cruel to man.

Answer 4

It's sad to say but their are some sick people who do it because they ENJOY it. No other real reason.
