Yup, and at the end of the day, it's all about him and his existential flaws. Even his love for Death, it's all about him, and finding something that gives him purpose in a justified concept. Be it romance with death, destruction, battle for the hell of it, his brotherhood and love for Warlock, or just simply doong something because he can. It's all for a psychotically, yet vulnerable personal purpose.
Which is what some people don't seem to get about his relationship with death and why it is tricky to make it work on screen. It isn't about romance, it isn't about love for a woman. That's not what his infatuation with Death his about. Both conceptually, narratively, and even symbolically, it is so much more but it is still about Thanos. Everything Thanos does is about Thanos and FOR Thanos, even him doing things for "death". When people really dive into the character, I think they can finally understand why some of us object to using death in the movie as a motive if the motive is purely romantic.
Especially with all that is coming out about Thanos now.
