Are they the bad-ish type? Because I think I have an idea.

Ehh, Ba'al is more evil than Teasl'c, in that the latter does what is best for his people but is also loyal, and since Ba'al gave his people some freedom, that means that he's loyal to Ba'al. 

Ba'al, on the other hand, is a cliched megalomaniacal evil alien parasite who happens to be self aware to the fact that he is a cliched megalomaniacal evil alien parasite. So he falls quite a bit higher up on the 'bad-ish' spectrum. He's also old, and abused time travel to get his current position.
