Is Humankind Evil?....

There are writer’s that call humankind evil.  Some describe humankind as insane.  Even among these commentators on human affairs there is no agreement about the existence of hell and ‘the devil’ who causes us to do bad things trying to capture our souls.  There isn’t even agreement about the definition and description and place in the lives of humanity of god. 
What do you think? and where do you get your ideas and beliefs?  What is your opinion of humans where there always seems to be war, violence, abuse, and so on?  Do you think that humans are evil? insane?  Or do you make excuses for killers, abusers, racists, you know the rest.   Do you blame it all on ‘the devil’?  Are you insane or evil if you lose your temper and yell at your kids?  Are you insane or evil if you lie to your spouse or partner about an affair?  about financial issues?   Do you think its ok to hate minor things like lies, gossip, etc but approve of war and using up the earth’s resources.     These are things we as humans need to think about.   Being able to think about things like this make us human.  But does it relieve us of being evil or insane?
