I dont have any tattoos but many do, and i dont really consider it "evil" only if it is a satanic symbol then it could be kinda like dedicating your body to the devil, but you could also have the head of jesus on your back or a cross on your forearm tattooed ? Why not?

I read from Catholic exorcists, that it is better not to have tattoos.... I dont know the official stance of the Catholic Church

I think Judaism is the strictest about tattoos, you cannot be burried traditionally jewish if you have tattoos right? What does Islam teach or Hinduism and Buddhism?
