I must say, he doesn't. What he has done for Sakura he has also done for Karin.

In supplementary material, Sasuke acts indifferent to being labeled a traitor and figures it has nothing to do with him. The moment he hears that Sakura is being threatened, he rushes to save her. She didn't even need him, as she fended them off herself, obviously, seeing as how she was Tsunade's disciple and all.

Don't think he's ever actually done that kind of thing for Karin. Not to mention that people conveniently neglect that Sasuke pushes Orochimaru for information claiming that the Shins "tried to kill [his] daughter and harm [his] wife."

The possibility of him having impregnated Karin is certainly possibly. But a lot of what we've been shown indicates that Sasuke does care for Sakura. However, anyone can argue that this might not be romantically so, everything's up in the air, I guess.
