Are there man-eating wolves

If a wolf is desperately hungry, I imagine, it would attack a human. They would prefer the very young, the crippled, or the old, since they are smaller or clearly aren't as strong as other humans. There are cases where even coyotes, which are much smaller than wolves, have tried to hunt children.

Nowadays, it's very very rare to find a man-eating wolf. Wolves, for the most part, fear humans and will keep their distance. It is thought, though, that European wolves used to be much more aggressive in the past (hundreds of years ago), and it was not unusual for a wolf to attack a human. Yes, but it is very unlikely that you would be attacked by one. The only situations I can think of are if...

A) The wolf is very hungry and there is no other food available

B) You are very young, weak and unarmed

C) You approach the wolf knowingly, especially if it has cubs or if it is wounded

Wolves never attack for the sake of it.

Not generally no. The only time a wolf if likely to attack a human for food is if it has lost its fear of humans in sub-urban areas. Once a wolf has tasted a human once it is not uncommon for them to continuing preying, which is usually when they get killed....

yes
they are meat eaters but don't eat people.
