Because it could mean that a precedence for batarian squadmates is set for the future, particularly if Balak is ultimately recruited. Of course this would be countermanded if Shepard was a War Hero. As for the numerous humans killed: majority were Cerberus or fiercely devoted to a religious cause (i.e. Biotic extremists or Major Kyle followers).
