My stance says nothing about punishment, imprisonment, or retribution, and is more about recognizing that there are things humans can do to each other that are irreversibly damaging, and that is not an okay thing to do, and recognizing that you have caused someone irreparable harm that will never be "fixed" is the emotionally mature stance. I'm not even saying you should wake up every day with a weight on your shoulders for killing someone, but rather it's something you should keep in mind, and victims owe nothing to the people that harmed them, and I do not believe expecting victims to tell people doing bad things "everything is okay" is beneficial to society. Being without forgiveness from those you harmed is not equivalent in any way to being in prison for life.
This is generally unpopular among liberal and left leaning spaces, and is only marginally popular in right leaning ones.
