You want to equate my belief, that the punishment should fit the crime by saying “a killer deserves to face death to right the wrong” to being a killer my self?
Everyone wants a punishment that fits the crime, but we disagree what punishment fits what crime. You want the state to kill people who you think deserve to be killed, but you also know that this will lead to innocent people being killed by the state, which is acceptable to you. How does that not make you complicit in the murder of innocents?
Then explain to you why you shouldn’t have that view point? Pre-emptively?
Why you shouldn’t have what view point? The one that leads to innocent people being killed? Because it leads to innocent people being killed. Generally, any view point that leads to innocent people being killed is one you shouldn’t have.
