This is a single-player game, so accusations of "cheating" are a complete nonsense. You're not competing against anyone; you interpret the rules to fit your own style of play, and you play the game the way that suits you best.
I'm also of the opinion that it's OK to use game editors to counteract bugs, such as the Gharik's Lab Key bug, or to compensate for the loss of of reaction time caused by the bugs in the armour skills.
It's your game, you bought it and paid for it (we hope!), and that gives you the absolute right to go ahead and do whatever you like when playing it. Have fun!
