"It's better to be alone than to be in bad company."

If one knows befriending a particular someone doesn't benefit in any way, and if they know there are better people to befriend, they shouldn't do so. Sure, they'll experience more and view things differently with them, but that doesn't always make them "friend type". Whatever a friend might be, it isn't someone who leads them to wrong and scar them forever. Others may feel incapable of making friends, but there are actually some "positive" factors of it.
