I don't want to say that emotions are all bad but chaos is a path of no return. There are probably some examples of last minute redemption but usually once you take a step down the chaos road your soul is toast.
This does beg the question of "What's your point?"
Yes, extricating yourself from Chaos alive is nearly impossible, especially considering there's literally noone around to help you do it ("Hello. My name is Arcastus the Thrice-Cursed, Lord of the Fey'rin Abyss and Despoiler of Coronia - and I'm a Chaos worshipper" "Hello Arcastus!").
This merely means that you've got to watch your own actions all the more - Assuming Corruption affects your mind as well and makes you more like your deity, viewing their emotion as an end instead of a mean, trying to stay as low as possible corruption-wise is going to keep you on your original motives for turning to Chaos far longer than those who embrace it and lose themselves. Should you wish to stay human, you can't fail your deities too often, you can't please them too often and you can't call on them too often. In fact, it's probably safest to remain unaligned as that shuts down one source of Corruption points outright.
And of course, someone truly dedicated to his ideals shouldn't hesitate to put a bullet to his brain once he starts losing sight of them.
