Destroy the idea that good DMs should be trying to make the PCs lives miserable. Good DMs facilitate good stories. It’s not about control and setting up every encounter so that there’s like an 80% chance of everyone dying. It’s about making sure everyone, including yourself, is having a good time and if you can’t have a good time without ruining the fun of others, you shouldn’t be DMing (If your players consent to really high-stakes gameplay though, more power to you).
