Despite his differences with the other Ricks, he's still A Rick, so his using unethical practices to get what he wants is nothing surprising. I believe Crystal Gem Pearl would see what she once was before joining Rose Quartz, and from all of her time with the Crystal Gem Rebellion and even further with her time with Steven, and may feel pity for them for still following there mistresses without question, and may even wander what her life would have been like if she never met Rose Quartz and learned the value of being your own person.



And finally, the other Ricks may be divided as of "Tales from the Citadel" it is clear that other Ricks have radically different personalities from the divergences of alternate possibilities (which would include other versions of Pearl-Rick), so some may admire his ballzyness for going that far and succeeding, some may be jealous that he found immortality (and got to have his own set of boobs to play with) some wont care, others will think it stupid and a waist of time to make himself a lady. Pearl Rick "herself" would not care what other Ricks think, mostly from the fact that Ricks hate each other more then they hate anything else, even hating the Ricks that have left him to die, forcing him to take this route. So, more of an excuse to give every other Ricks the middle-finger then the usual.



If you want more elaboration on what I have written, let me know and I'll try to answer as best I can.
