See I like cartoony evil in some games because yeah sometimes I just want to have a MUWAHAHAHA character that just doesn't give a damn it's entertaining. HK's pretty good in either game though I'm more fond of him in KOTOR 1. I did play it first after all. I got tired of Kreia quick yes she's a great plot device but honestly I could only stand her on neutral characters though I did love touching the graves after she said to leave it alone. To each their own. 
Gonna go a bit off-topic here
My opinion of moral choice stems back from games like inFamous, BioShock etc. where the "evil" option is usually so cartoonishly villainous you'd have to be Jeffrey Dahmer, but even he wouldn't have called himself evil. The problem doesn't lie in as much about the villains being pure evil, as it does with how they are characterized or how utterly devoted they are to their own plans, being in control. A villain doesn't need to be sympathetic, or carry some sort of emotional weight to their schemes, they just need to be engaging. Hence why I like a character like say.. Adachi from Persona 4 and dislike a character like Trevor Phillips, and it's not necessarily because the latter is a psychotic (I love Brick Top from Snatch) it's because his actions make no sense at all, and it makes him become a really unlikable character.
Every GTA & Saints Row game has you play as a complete sociopath-tic a-hole, but the difference being the former demonizes organized crime, and the latter romanticizes it. Despite spending most of the games mowing down people with an ice cream truck, the protagonists, are usually always in control of their actions, they have in their closest allies, they are conventional (Well, the Saints Row protagonist notwithstanding) but they have an overall strong motivation and carries great devotion to it. They do what they do because they want money, so they move up in life, because they believe money is the answer to absolute freedom, and the part about being someone.. Whereas a character like Trevor does what he does because... well, I don't know why he does it at all. The sort of renegade "risky" non goody two-shoes karma path I can get behind.
Going back to KOTOR 1 quick -- Had Malak's characterization not been based of the Guide to Generic Villains, then he might have become a credible antagonist. Blowing random **** up is not how you take over a galaxy, Malak ol' boy. 
In retrospect -- I liked the list and it's made think on going back to work on my own list
