I'm currently unconvinced either way on this matter. However, enough arguments have been raised that I think this is worth the time of every reader to think a good deal about.

We may be using different definitions of "care". Mine is exactly how much I'm motivated to change something after I became aware that it exists. I don't find myself extremely motivated to eliminate the suffering of humans, and much less for animals. Therefore, I conclude that my priorities are probably different. Also, at least to some extent I'm either hardwired or conditioned to empathize and help humans in my immediate proximity (although definitely to a smaller extent than people who claim to have sleepless nights after observing the footage of suffering), but it doesn't generalize well to the rest of humans and other animals.
As for saving the replica, I probably will, since it definitely belongs to the circle of entities I'm likely to empathize with. However, the exact details really depend on whether I classify my replica as myself or as my copy, which I don't have a good answer to. Fortunately, I'm not likely to encounter this dilemma in foreseeable future, and probably by the time it's likely to occur, I'll have more information to answer this question better. Furthermore, especially in this situation, and in much more realistic situations of being nice to people around me, there are almost always selfish benefits, especially in the long run. However, in the situations where every person around me is basically a bully, who perceives niceness as weakness and the invitation to bully more, I frankly don't feel all that much compassion.
Yes, I'm using 'care about X' to mean some combination of 'actually motivated to promote X's welfare' and 'actually motivated to self-modify, if possible, to promote X's welfare'. If I could, I'd take a pill that makes me care enough about non-humans to avoid eating them; so in that sense I care about non-humans, even if my revealed preferences don't match my meta-preferences.
Meta-preferences are important because I frequently have conflicting preferences, or preferences I need to cultivate over time if they're to move me, or preferences that serve me well... (read more)
