Why would they regret it, they are all in paradise with 20 underage virgins each right now, seems they are the lucky ones of peace
I will love to hear christians and Jews mocking this belief while still banging on about there own fairy tales of peace... I might add they believe this so heartily that they will blow them selves up, how many if you are so commuted to the faith to do so likewise
obviously its all pure bullshit, we all know Santa isn't real
