Yes, it's still practiced even in our society, although exceedingly rare. Google 'Rotenburg cannibal' for a relatively recent story that made headlines around the world.

As for my opinion... it seems sick and depraved, and I truly can't fathom what had to be going on in the minds of the people involved, but I pray for their souls to find peace with what they've done.

Probably should have stuck a trigger warning on this, because even as far as cannibalism goes, this story is rather... extreme. Suffice to say Rammstein were so impressed they made a song about it. 

Of course there are more examples of cannibalism in the modern world, like people getting stuck in remote areas without food having to resort to eating the dead in order to survive. This guy took things a bit further though, so... consider yourself warned.
