How is it that some atheists are good people despite not believing in God?
Take, for example, me and my brother, we were both born Christians and more specifically Catholics, my brother is a wonderful man even though he sometimes behaves like an a**hole 
But despite everything, he is a very good man, and he is an atheist, he does not like the church and the Catholic church in particular, and about other Christian denominations he says that they are hypocrites 
l also have a friend whom I met on one of our Polish forums for people with psychological problems, I am an Asperger Syndrome and my friend ADHD says that his wife probably has Asperger.
He said that at school they were both outcasts and they fell in love, that because of their common stupidity she got pregnant at the age of 16, she told him that she could go to abortion.
He felt so badly offended that she might even think that he would like her to undergo an abortion, that despite the whole situation, he would decide to give birth, that he would support her for the rest of his or her life, but it's her decision.
Now they have several children together, he does not go to church because he thinks that God does not exist, at least that which the Bible speaks about, but when the issue of liberalization of abortion law in Poland is raised, he always supports "pro-life" and supports wife, all anti-abortion petitions organized by the Catholic Church in Poland or Protestant churches, even though he is not a believer himself
He says you don't have to be a Christian to be decent
