You are making a lot of assumptions here.
First being that this is gratuitous torture, which fits into the pattern where you regularly assume stuff I propose to be comically hyper-Evil for shits and giggles. I do in fact not give a rats arse about Crasters comfort, but I'm still significantly offended by your implied accusations.
Second being that you somehow need to testfire an electric chair 50 times before it works. If this is how you design things, please be not offended if I stay the hell away from everything you ever made.
Lastly, if you want a functional afterlife, you need the means to recycle the souls of sentients. Heaven is so much more broken then the other two Upper Planes because they no longer can do this. Unlike Angels, Azatas, Guardinals and so on, who are in decline, Archons are a dying species.
