you have to decide which disciple you want to focus on whether it be medically, theologically, psychologically, socially, etc. in the construction of your arguments.
as it is currently, it is obvious that not much thought has been put into the topic. the ideas are jumbled and the disciplines overlap. these issues give way for contradiction. you should do research instead of relying solely on your morals
Just a curious question to op hmm : Why do you think murder is punishable by death? Because like you clarified later, murder can be for various, various reasons. Revenge, self defense, serial addiction, under substance influence, accidental, justice (something you are proposing is murder for justice; ie; death penalty). What is the institution of measure you'll use to decide whether this specific type of murder is worthy of a death penalty? Don't you think it might get messy and unfair sometimes? Just curiousss. But I agree with death penalty for rapists and pedophiles.
I believe it should be punishable by death because a life is not something you can give back, taking a life is not something someone should be able to come back from, to be forgiven for. You took someone's life, so why do you deserve yours? Especially if they've taken multiple
And I don't necessarily believe it will be a smooth and easy going process, nor fair. And there's nothing to measure unless the murder was committed in self defense or for a good cause (but then there is argument for what a good cause is), if not either of and intentional I believe the perpetrator should be put to death.
Killing someone by accident (ex:Car crash or workplace mistake) shouldn't be punishable by death

Okay its 6 in the morning where I am and I just had a large thought bigger than my body. But I need yall to listen and not put a pitchfork to my throat
Abortion is murder, just listen to me okay? Even if the fetus in the early stages is more of a leech than a person, it's still going to become one no? So deleting it is killing a person but this is were my main focus comes in
Is all murder unethical? Is all murder bad?
If you were told that the baby you were carrying would be the next Adolf Hitler? Someone like Ted Bundy or Jeffrey dahmer or maybe even become like one of those boys that killed James Bulger? Would you not want to get rid of it before it gets a chance to spread evil? To do bad?
But of course we as humans can't predict something like that but even with the people we know have done bad things like this, we shy away from the topic of what's the right thing to do with them. I don't believe it's bad to kill a murderer, it shouldn't even be debated. You took someone's life, what gives you the right to continue living?
"But what to do about pedophiles or rapist? They haven't killed anyone." But did they not do something that effects the victim in ways that can't be undone? That lowers their quality of life in general? I personally feel its on the same level as murder, and both should be killed.
This is actually a topic for an essay I was supposed to be writing but I chose a simpler one but I wanted to yap about it somewhere
