no for Thanos as he tends to have too much complexity to be a CM/PE (not that you can't have complex PEs) - Thanos is usually the "unfettered" and as such embodies a sort of "beyond good or evil" thing... Thanos can destroy the multiverse, yet he can also heal it.. all depends on his plan at the time.

so far his MCU counterpart doesn't seem to do anything to suggest he doesn't also play the role of an unfettered, which would make it much harder to qualify.. remember in original Infinity Wars (comics) Thanos never lost, he gave up because it bored him and he wanted to see what it would be like to lose etc..

so I don't see Thanos qualifying unless they mess with his character (which would be a darn shame, really) - Thanos is not Darkseid, he isn't all about "eviler than thou", he often helps heroes only to stab them in the back and I believe Thanos has deep, deep respect for Adam Warlock.. not sure if Warlock is in MCU yet but if Warlock is included in MCU Thanos will almost certainly retain that respect, as it is one of Thanos' main traits.
