Has Catholicism destroyed the aggression within you and made you victim to the world?

Christianity was invented by Roman emperors for their slaves to keep them in . That is why it emphasizes obedience and rejects ethics, it insists on suppression of natural urges and rejection of worldly pursuits. So you are right that Christianity turns good people into helpless victims in the cruel world. However, it does so not by destroying the aggression within people but by indoctrinating them with a skewed worldview. Christians are actually quite aggressive. Some of them are willing to kill in the name of God and almost all of them have no respect for the beliefs of others.
