We believe killing is wrong. And the law says that an unjustified slaying of another human being is 'murder' and illegal. Yet religions give numerous justifications for killing people. If a religion says killing someone is okay, legal issues aside, is it then moral to kill? This isn't a legal question but moral one then. If killing without religious sanction is immoral, is killing with religious sanction moral?
If you take out war, and execution of criminals, I still could find several reasons why I would kill someone.
1. Self defense (this includes someone breaking into my home, and defense of my family members, or someone else who is in danger of being killed).
2. If someone killed a close family member of mine, and it was without a doubt, yet they got a high priced lawyer or got released due to a technicality, I would have no problem ending their life, and I would have no problem if that brought me the death penalty myself. (I do believe in an eye for an eye).
There are probably more reasons, but I cant think of them off the top of my head. Are any of the reason morally right? I believe God would forgive me for the ones I listed above. Would I want to kill someone, NO! That is not something I want to have to see every night when I close my eyes.
