Well, morals are usually something society-induced, meaning different societies have different morals, as in cannibalism, something our society sees as one of the worst things there are, might be as normal as it is to you to eat animals to a society that is traditionally cannibalistic. Of course, people here will freak out and say "that's just wrong, no matter from what perspective", but for them it'd be the most regular thing ever.
That being said, there is a sentence connected with the wiccan religion that goes "an it harm none, do what ye will", which is something I can strongly sympatize with, even if it simpfies things alot. Basically, by this, killing someone is bad, but, as opposed to what many christians preach today, homosexuality isn't, for example.
I should not post in intelligent debate in a state of insomnia.
