Because what goes around always comes around! Whether you get evil returned to you immediately in some form or later,even in the next life,as karma,it will come back to you.We are born here in this Earth plain to experience the life experience and work through past wrongs to others who we have wronged and or to have more happiness with other's who we could not get enough of in our past lives together.We all choose to be on this planet and interact at this time.There are no accidents! We also have free choice[good and evil]the original sin going back to Adam and Eve,that God gave us and is a dichotomy in our lives;the daily struggle between good and evil,the good the bad,the up the down,etc.We struggle to be good while tempted like Eve in the Garden of Eden...between advertising and competing with our neighbor's.We think we should have this and are brainwashed into believing we need things,when they are not needs at all..just foolish wants.I believe those are temptations of evil.We all should know right from wrong..like it is wrong to kill,and rape,and steal..the Ten Commandments.We should follow them as God created them as His laws for mankind..period.We should be afraid to do evil for that other place,Hell - where we will go for all eternity,and or the Hell that will befall us here on Earth such as prison if we commit such act's that break mans law's also.We should always fear God! If we follow the good,and do good always,we are rewarded by God/the Universe by following our intuition and the synchronicity of life flows and we feel the energy of God being distributed to others through us and our actions.or at least I do.To me that is reason enough to follow and continue doing good acts such as charities,etc.I have been regressed and have seen my past lives and in one of them I was touched and blessed by Jesus,and I served Him until I died.In my current life,I am gay.Does that mean I am going to go to Hell? Am I evil because I am gay? No.My soul that was blessed by Jesus is the same soul now as it was then..and I know I am going to Heaven when judgement day rolls around,because a soul cannot change it's roots..it is permanent..so it is the same..and I was created gay for this life..that is all the assurance I need.I choose to be good and love and give hope and joy.Peace.
