Just one thing, Kylo doesn’t literally feel the pull to the light.
In TFA, Kylo Ren is established as a character who has a desire to be the bad guy for the hell of it, he wants to be on the dark side and be evil… but deep down, he acknowledges that what he is doing… is wrong; he wants to get rid of these goody-goody feelings forever, and it is for this reason he attempts to communicate with the charred helmet of Darth Vader…
…and why he murders Han Solo — he believes he can further himself into the dark side and permanently erase these goody-goody feelings; it is for this reason he is literally thanking his father, for his murder seeming to be permanently erasing his goody-goody feelings and ensuring he remains on the dark side for as long as he lives. When he does commit the deed, it does not work — in fact, he literally regrets it! He acknowledged how wrong it was for him to murder his own father, and this leads him down to the path of his failure.
Kylo Ren only used “the pull to the light” in TFA as a figurative way of saying that, deep down, he has these feelings that what he is doing is wrong — he never meant it literally.
