Meh, if the game is seriously taking the cake and running with it, i have no qualms with cheating. I usually play games on the highest possible difficulty because if you don't challenge yourself then I don't really see the point of it all. I'd never cheat on multiplayer but not really through a guilt reflex, more like if you did, there would be not much of a game left. And that's what I paid for in the first place! Spawn camping: why? It's just like a target range, only somehow more boring. Nuke boosting (or otherwise boosting), aimboting etc just remove the GAMEPLAY part from a game. Same with hacking. If these pointless rewards (a high KDR, the nuke emblem, 10th prestige etc) matter so much to you that you'll cheat to get them, then you have to wonder why you play games in the first place.
So would I feel guilty? You decide.
