- The death penalty involves intending to kill a person.
- Therefore, the death penalty is always wrong.

I’m against the death penalty, so I’m not sure what “moral position” of mine you’re attacking exactly. Our only point of friction so far has been over the use basic logic when formulating strong opinions.
