To add to what Arka said, it's not like people use debug to break the game (tho, I must admit, sometimes it's fun to change shit and see how far you can go) or anything evil. I'd bet most of us use it to avoid grinding for evs and changing natures/ivs/abilities (something that should be on any game at this point); making custom runs possible, etc.
If anything, I'd be proud to see people showing interest in my game, even if they're asking for "cheats", that means they enjoy it and want to play it.
