Unfortunately there are a lot of christians who don't understand the difference between the devil's deceit and Gods wisdom, and they are the ones who get a lot of attention because people like you push irrational stereotypes. Christians are supposed to be non violence and follow Jesus' path, so you can't use the ones who don't follow Jesus against the ones who do.
All your friends who experienced spiritual stuff only experienced lies from Satan. He gives a small price of evil power and whispers lies. If you don't believe in God by now then your 'spiritual experiences' were not valid.
Cherry picking things out of context and mislabeling them? If a bunch of evil satanists decided to do a terror attack on the east coast, would it be considered evil mass genocide to sink their ship and kill them before they attack the innocent?
Sacrifice is dead. Jesus sacrificed himself. By spilling his own blood, you can now be forgiven without doing it yourself. What is immoral about it if it is necessary? I'd rather be sacrificed than burn in hell for eternity. Besides, If they believe that it is good, then let them do it. They gave their own consent. That's how everything works according to you atheists, 'If they both have their consent and they're not hurting anyone else, they should be allowed to do it'.
Not to mention, you don't take into consideration that all God does is good, even if you don't agree with it. If you listen to the devil, you wouldn't agree with God. So if Hod does something 'bad' there is an explanation for it. You just need to try and find it.
And yes I read the Bible, but unlike you I actually understand what it says. Stop circle jerking to your own invalid misunderstandings of God.
