It's not him doing it, it's the humanity. Why should god touch something the humans have been starting? People always have to learn / feel the pain (in this case) to actually learn. Just touching that and remove all weapons or however you imagine it (probably like in a game) would be plain wrong in my opinion. People sometimes just have to learn what they actually did/supported when they lose someone. If it is your time to die, it will be your time. Sure you are always upset than and probably nothing can change that on a normal human
