Well, there is certainly a lot of grey area within whats considered right and wrong, and how much one can push the border. And the individual, defines where their own borderline between right and wrong and the moral tension within those restrictions for him or her selves. So people like Bush or Blair or Osama may have defined their own lines of morality, and filled in their own preferences to fill in the grey area to ultimately decide what is considered right and wrong and what God has intended. And sometimes they could feel they are just simply doing a "justice".
Or theyre just not thinking...not thinking at all...
It's a matter of good and evil, yeah but whos evil and whos really good, it seems there are few good people in this world, and many evil people who believe that they are good.
Now wait.....
No religion ever requires its followers to be perfect. We are but humans, and we sin. Theres no stopping it. Not everyone in this world kills or commits vile acts of crime. And within the most twisted minds and the most innocent minds, there is always a sign of good. It could be burried, or it could be voluminous...but upon our birth, we invested some good within us. But we all commit sin, so contrary to the good, there is also an element of evil within us. These sides create tension within ourselves through life. Evil is the side that is easier to follow, so that can prevail more then good, but the stronger the person is, the more they can fight it.
Only the extreme people can truly be considered "evil" or "good". Certainly there are heroes and there are twisted minds. And often there are more sinners then heroes, but you simply cannot make a huge generalization that the masses are more evil then good. Good people typically can commit sin, and evil people are often capable of comitting good deeds.
But I understand what you are saying. The people that are in power are generally the minds that are corrupted or do more visibly bad things over those who do beneficial things. And these people in power are often representing a larger group of people. But remember, this larger group of people do not, necessarily, follow the same ideals as their corrupted leader. So while people like Bush and Blair are going to invade another nation that they really shouldnt, that doesnt mean that all the people they represent would want to do the same thing.
Those who truly have lost control of their minds and consider themselves "good" but are evil, are really just not thinking right anymore.
Those who commit evil things that cause thousands to die under for petty reasons, and call themselves good in their religions are wrong.
