“Some people are just bad” is a core conservative belief. They don’t believe in harm reduction for drug addicts. In fact they want the harm to happen, and ideally for it to be fatal. Because these people are bad, so let’s get rid of them.
They have the same mentality about criminal justice. Some people are just bad - criminals. Give them the death penalty. They don’t want to talk about rehabilitation or small improvements to the recidivism rate. Some people are just bad, they think, so lock em up and throw away the key.
Of course, most conservatives have either done drugs or committed a crime, but the whole “some people are just bad” concept never applies to themselves in their own minds. Because some people are just good too, and doing bad things doesn’t change that.
So, conveniently, they themselves can get away with any kind of wrongdoing, forever. But a single transgression by another person is a good justification to simply end their fucking life.
It’s such hypocritical, violent, hateful mentality. Humans have succeeded as a species by coming together and looking after one another. This mentality is positively inhuman.
