Hmm. I doubt that's how the Warlock would work, but it might be cool that, as he grows in levels, his powers become less and less dependent on his patrons, as he manages to shake off their influence on him (but keeping the good parts

)
Sorry but please reread the description again, every level the warlock gains puts them FURTHER into hock with their patron NOT LESS.
Hmm let me try and put this into as clear an example as I can; remember Star Wars?
Anakin Skywalker starts off as a prodigy of the force, he can understand and command powers those of his own age have trouble even comprehending but he suffers from an overdeveloped ego, his pride and ambition far outstrips the safety his teachers re trying to instil in him and the Emperor uses that to secure him to his side, this is the past you're describing he continues in his service becoming more and more powerful for his union with the dark side and in return he has suffered terribly, he caused the death of the woman he loved, the woman he originally used as his excuse for turning to the dark side, later on he finds himself crippled and permanently wears a suit of life supporting armour enhanced to keep him alive and restore some of his lost abilities most notably he is in pain for the rest of his life.
In the end he turns back to the light to save his son and in return is abandoned by the dark side he once served without which he begins to die the price he has to pay for his breaking the pact.
This is my point, this is why I said I would only consider a warlock if the character concerned would have to multiclass to get it and why I have always considered it a prestige class and NOT a core class.
To you it seems its just a means of gaining power and that power has no consequences, think again.
Ultimately its the dm's province but unless you are the dm or your dm doesn't understand this will NEVER be the case.
Okay just read that bit about two opposing examples of warlocks, curious albeit valid but wouldn't it be better served by using it to see if the recipient is worthy of redemption after all exposure to something that pure should elicit a response whether good, bad or merely indifferent but how would you handle that?
Would the holy version be able to tell if they've succeeded in turning their adversary from their dark path or is this a repeat of all those lawful stupid paladin problems?
Any chance of an example of nature's verison of this or fey?
