In my opinion, Muslims love the life of Christians, and are just jealous their own religion does not allow them freedom. They are very tempted to live a secular life, but angry because they are tempted. They are often just full of anger because they are tempted, and want to destroy that which tempts them. Anger is normally fear, and I suppose fear of going to hell makes a few people real problems. For me, I ignore shame and guilt, it is the least productive feelings, but do try to avoid things that make me feel guilt or shame. While many want to do shameful actions, and then say they are a good person. Humans are slaves to their temptations, and great entertainment until they get violent.
