I slit dog throats
This makes me feel rather uneasy. Why would you do such a thing?
I want them all to suffer as much as they can
There are human ways to put dogs down. What you're doing is cruel, depraved, and against the law. You need to seek psychiatric help as soon as possible.
Don't be a fucking pussy, you wouldn't have an issue if I slit your throat.
You need to stop talking about killing things. It is very cruel and no one will want to be near you.
