The Aztecs had no problem sacrificing people, and many sought it out (it's theorized) given that it guaranteed you a place next to the sun and thus in paradise, eternally drunk.

Extremists even today believe in a paradise-after-death if they sacrifice themselves for god. To a lesser extent, self-flagellation (whipping oneself for religious purposes) is still prevalent in many cultures and sects of e.g. Christianity/Catholocism today.

"Right" and "wrong" change over time, and with culture. Thus they are subjective - there is no objective "right" and "wrong". In this sense, your last sentence relates two identical things - what you might agree with and disagree with are your own perception of "right" and "wrong".

It's a somewhat flawed and (in my opinion) dangerous way of thinking about social interaction and morality.

E: Because I know this will be mis-interpreted, let me be clear: the website in question is, in my opinion, abhorrent - but I think it's dangerous to celebrate a large company taking it down on the grounds of morality. I understand it was taken down as it specifically violated a pre-existing clause in their ToS which makes it make sense in this case. But to say that this is a great thing and we should do this for people that are "wrong" is beginning down a path that nobody really wants.
