This guy has no business in a light RP game... I wouldn't even try. It'd be rude.
Excellent. Now that I get a little more of the baseline it's less worrysome.
Wow, that's totally different from my take on DM'ing... for me, its all about 'babysitting players RP experience'. Unless that doesn't mean what I think it means. A DM provides a series of (hopefully) interesting challenges to each individual player, and the group. How's this guy different? Do you mean he'd be a DM time-hog?
Maybe the kids you babysit are different from the ones I do then.

There tends to be a lot of "Don't climb on that, it'll break. Here, play with this. Don't touch that, it's hot." And, of course, the ever fun holding on to a screaming child that tried to run heedlessly into the winter shopping crowd. When I use the term in a gaming context, it tends to be similar. For example: when I need to watch for appropriate behavior, make sure I offer enough fun to entice the players into something, pull people off of the TV, make sure everyone knows that we're playing at 6:30 on friday, and make sure that the cleric doesn't make everything into a mess by declaring the evils of what the party's doing till everyone is too frusterated to do anything.
With regards to your character, my worry comes from the fact that he's trying to push the boundries. Now hopefully my worries are unfounded because you're better at it than my players and I. However, in every instance that I've seen someone try to 'push the boundry' it ends up bringing the game down if left to its own devices. Ultimately the characters lead to discord, don't make effort to fit in, and drag the other players at the table down. I prefer situations where I don't feel the need to check my players' behavior.
My specific worries with this chracter involve the potential for doing rotten things, and using "but I was just too weak to resist!" as an excuse. There's a thick line between that and being one of the guys who plays an evil character but says he's good, but it's a line you're toeing nonetheless. If you combo that with the fact that you're playing a paladin and paladins do have the whole "You transgressed? *BAM* No more powers for you!" attribute, there's a horrendously huge potential for conflict.
How possible do you see this situation:
"John, that's it. You're taking jewelry from the mayor's wife who you just slept with. You're a fallen paladin now."
"What? That's not fair!"
"Yes it is. You're being evil."
"No I'm not. I'm just being weak. It was so shiny!"
"No. That was an evil act."
"Man, you're such a jerk."
It's exaggerated, of course, but I can see that sort of thing happening with this character in the wrong situation. Hence, the need to handle it with extra attention and care, or repeated sledgehammerings.
Of course, if the answer to the question "Do I trust you to play a reasonable chracter and contribute to the fun of the game?" is "Absolutely." Then the whole issue is null and void. Why? Because we go back to my main paladin rule (and typical game rule in general) "don't make me question you, and I'll assume you're correct."
Oh yeah, lots of monolouges in as booming a bad British accent as I can manage...
Heheheheh. Excellent. Sounds fun.
Anyway, hope that clarified what I meant.
