Do you think System of a Down is an "Antichrist" band?

Now I love there music and I'm not putting anything against them but there song Chop Suey (which I still do like a lot) just seems kind of anichrist or however you want to put it. In the lyrics they say, "I cry when angels deserve to die." So I don't know if that is supposed to be bad or good in a chrisian way.... What do you guys think?
