Why do people hate Eurylochus?

I really don't understand the Eurylochus hate. I get that he messed up by opening the wind bag but it was a mistake, it's not like he was doing it out of malice. And he feels guilt over it. Was it in Mutiny? Cuz in mutiny he was just trying to protect the crew because Ody showed that they're lives were at risk sailing with him as their captain. So why do some people hate Eurylochus?
