Ok so your a straight forward person - you have just as much right to post as I do...right? Even though I may not post in the same way.

The mother may have had difficulty dealing with the death and found comfort in other men. One possibility? Healthy way to deal with it...probably not

Trust me I have had intrusive thougths since I was twelve - almost 25 years later I still have them. Then again I didn't seek help until two years ago.

If you generalize - I can see why you would say humans are evil and arrogant. Many are not as you describe.

Everything has an opposite...

up/down
left/right
north/south
evil/good
cold/hot
love/hate
etc.

So if you see that then there are just as many "humans" who are not as you describe...
