pro-life means that you believe only God decides who lives and dies though, right?

^pro life means that I'm against abortion.

and to be against abortion, you must believe that only God has the right to decide who lives and dies. correct?

I believe that if someone is a danger to mass amounts of people, then they should be killed.

I think that in many cases the death penalty is a necessity, such as in the case of killing Osama Bin Laden (I know he was shot on sight but he is an example of the type of dangerous person) but I'm also wary of it in many cases. Sometimes people are convicted and sentenced and turn out not to be guilty later on. I wish that those who decide on whether or not the death penalty is used would only do so when they are absolutely sure of the evidence. I'm this way because of course, I don't want innocents to die, like Jesus did. But I can't do anything to change the rules or anything so. My opinion is pointless. But hey.

I get why it is sometimes absolutely necessary but when people decide to kill other people under any circumstances it bothers me

but we kill people to show that killing people is wrong which makes no sense
