my life????

What is right to do...what step should i make..???
To walk aginst the blood or next to it....? Why some people are so selfish ..and other too kind?
Why the good people had hard life and the bad easy one? Why some doesn't really realise that they hurt somebody even take this person to the hospital....
Is the humanity make us better people and happy..or just make us weak and let the other to walk over us? If the only reason to be good is the Eden...then why the way we are walking on is like hell? What is the good point to change something when in the other moment everything get down in a small spots...
