"Anakin, remember when you dreamed your mother died, and she totes did, well now that you dreamed your wife, your last loved one, would die, it's gonna happen. So how about we try to pierce the secret of eternal life, you and me, since, you know, you and I are the most powerful force users in the entire history of the universe, we might be able to figure it out, there is no guarantee of course, but it's worth a shot isn't it ? I'll only help you in your quest if you do my bidding. "
The only thing close is that Anakin did lose himself in the process, he ended up wanting to overthrow Palpatine as soon as he learned how to prevent death, and become emperor himself.
So Kylo might be drunk on power too, but right now , which is with literally no backstory on Kylo's motivation, he is the definition of a pissbaby.
Vader never tried to kill the ones he loved. It was the point of the OT.
Comparing Kylo and Anakin on their actions is irrelevant if you don't take into considerations the motivations. They might act similar on some aspects but they are nothing alike mentally, as far as we know.
