Bad as in malicious or bad as in they offered/you asked for their advice and it didn’t work out? Because if it’s the later, that’s an unfair burden to put on your friends or anyone else. People can give great advice, genuinely want to help, and it still not work out the way you wanted. If you require friends to be 100% with their help, I’m not sure how you have any friends left.

It’s possible to give good advice that doesn’t work out. I have no hard feelings about that.

It’s also possible to give bad advice wothout being malicious.

I have some friends who don’t give great life advice. We’re still friends, they’re just not the friends I go to when I need advice on a big decision.
