There is no more sinner and less sinner, it is still a sin. This is also applied to cloning and hacking.
Thou Shalt Not Hack and Thou Shalt Not Clone eh?
and how is manipulating a video game sinning?
well, Hacking is 100% set in stone as bad, seeing as it is manipulating the game coding into creating things which you normally couldn't get, or manipulating odds and stuff.
Cloning, this is an ethical issue in Real Life, and in the pokemon games. Some people say it is the same as hacking, others think it's alright because it's a glitch. All it does is as it's name says, clones the pokemon.
Honestly, I think Hacking is bad, UNLESS it's for an event item you can't normally get, but I think cloning, even though I don't do it myself (I once did it out of curiosity on a swellow, it worked) I think it's alright, but could be evil if used in the wrong hands.
