c137 and prime

okay so I watch this show religiously so I feel stupid asking this, but did prime kill diane bc of c-137? was it bc prime thought c137 believed himself to be “better” than prime and every other rick bc he rejected portal travel? if so, do the other ricks know that their diane was taken from them bc of c137’s actions? i’m basing this off of s3ep1 when the fed agent and rick were inside of his mind. the thing is, he fabricated the memory, is was that the truth or…

The answer is probably within the ep’s and im just forgetting so pls correct me or help me remember !!!
