Swedish prisons don't even look like prisons, they look perfectly comfy and a great place to live, so life imprisonment please! Even if I don't get sent to a Swedish prison, the thought of dying is horrifying to me. I don't care how people kill me if it was a death sentence, needle or not but think about it... the wonderful life you may have lived before, is now gone. All gone. And the thought of not knowing what is ahead of you is the most terrifying.
Also prison can actually do you benefits surprisingly. While they might not be the best paradise on Earth they can help you develop, change into a better person, see where you all went wrong. Even if you're confined 24/7, at least you have time to think, think about your wrongdoings and try to change them. Also you don't have to worry about mortgages, bills and you get free food, even if it might not be of the best quality!
