Bad Guys

I worry the villians aren’t enough. Since most of my stuff is written within the perspective of the heroes, it’s easy to make weak villians who don’t bring the fear. What is my villians aren’t sinister enough? Can I amp them in some way? Can I just make sure they’re actual forces of antagonism and not just annoyances? Basically, are they bad, I mean really bad, or just kinda there?

I hope they’re okay.
