He paid his time so he should be allowed to go back to work. Same thing goes if his employer was Wally World. The only time I feel a felon should not get their job back is if their crime could be related or used against their employer. If you get a felony charge and go to jail for insurance fraud then you can't work for an insurance company again. Any other non related insurance company why the fuck not. You still need to eat.
Speaking of eating killing animals is fine as long is it is not for fun. If you hunt and either eat the animal, or use the animal's skins or whatever that is ok. If you are just killing a deer then taking a picture then leaving it there to rot that is not right. You are a cold blooded killer in my mind if you do that.
Same thing goes for killing humans. I wouldn't condone eating human flesh or using their skins but if you kill a human (random crime or in the armed forces and required to kill) you are a murder. Still you are wonderful for laying down your life for your country there is no doubt of that in my mind. You are a true hero to your country, but I sure as hell would not do that. If I was forced to join the military I would become a chaplain. I don't want to kill humans.
I wish there was a PETA for humans. We need a group of people to go after people who kill, enslave, rape and pillage humans in crimes all over the world. Animals are nice all all that mushy shit but we are clearly the highest on the food chain for a reason. And that reason is because we are fucking awesome and pwned every other species.
