Following Warlock means that you will not be an annoyance to the World of Pain.
Warlock really dislikes annoyances. Warlock does not favor any alignment.
Warlock wishes that you be at least of level 100 before you follow him.
He does not care of your PK habits, as long as you are fair.
He dislikes looting for no reason, and looks down upon it.

There will actually be some RP for him in here soon, when he quits being lazy.
Until then, you'll just have to deal with it!
