The "red shirts" dying DID have an impact. Not an emotional one, but an impact. Namely the fact that even AIZEN, the god-like chessmaster trying to rule the world and who is perfectly willing to kill in order to do so, didn't produce that many casualties during his 4 arc-long time in the spotlight. As in, the Wandenreich have him beat 2091 to about 50. That's the impact it had: it proved the Wandenreich were serious business about their goal.
