The master of EVIL!
This is my opinion on all of the crime organizations in the games:
Team Rocket (Kanto): I think the best and most evil group overall, as they actually do illegal things, such as robbing and vandalism. They also are huge and have much influence; they own a casino, Mr. Fuji is part of Team Rocket, Blaine possibly is, and the 8th gym leader is the Team Rocket Leader!
Evilness Rating: 9.5/10
Team Rocket (Johto): I think they did the worst act; cutting off Slowpoke's tails, and even mentions killing Pokemon, even. They lost much of their influence in Johto, however.
8/10
Team Magma/Aqua: They basically want to drought/flood the world. Have no influence. Don't really do anything except their main goal: drought/flood the world. However, have some determination.
5/10
Team Galactic: They want to destroy the world and create a new one. They have some influence, like their own commercial. They also have multiple buildings scattered across Sinnoh. Their motive is a little bit more mysterious and dark.
7/10
Cipher: Don't really have much influence, except by transferring shadow Pokemon through trainers. However, members are everywhere. Turning Pokemon's hearts to darkness is a horrible thing to do.
9/10
Snagem: No influence. Developed capture device.
2/10
Go-Rock: Not much influence. Cool guitar solo, though. Planning on ruling the world using the legendary dogs is good motive, though.
4/10
Dim-Sun: Haven't played the game, but I think they're much like Go-Rock.
4/10
Phobos: Not very well known, it's the evil organization in Trozei. They don't appear to really be doing anything particularly evil... Don't know much about the game, though.
2/10
These are just my opinions, though.
