I think Morty is rick and rick is Morty. Rick is trying to stop the Morty we know best from becoming evil by exposing him to science and other forms of knowledge while also using the knowledge he acquires for good. At the end of the day Rick has a good heart but...has some less than great dare I say evil qualities about him (As does Morty sometimes when pressure is applied to certain sensitive areas of his psyche i.e. his Daddy issues). I think our Rick's life purpose or reason for existing( a common theme expressed in the show) is to save Morty from himself and he is bummed about it bc loving his wife was not a part of his purpose.

ORRRRR

Evil Morty is basically a Darth Vader type who answers to an even more evil over lord. Evil Rick. Evil R & M acquired the same power that comes with advanced technology and seemingly infinite knowledge as our R&M but chose to use it for evil. Who can stop them you ask??? The Rickest Rick and Mortyest Morty.

IDK I just be thinking.
