Aldaris' statement is primarily about disobedience to the Conclave and the consequences of that disobedience (Zerg using Tassadar's reluctance as an opportunity to escape), rather than necessarily about sparing humans. The Dae'Uhl is a logical reason why a Protoss might be reluctant to kill an "inferior" race, and is not grounds for immediate "you're a traitor, never return."
Also, Aldaris later demands that Tassadar return home to Aiur, implying Tassadar's control of his own forces, and also the more likely consequences of Tassadar's reluctance to destroy infested human worlds. That is, some form of recall and court marshal. I mean seriously, a guy is reluctant to kill, and their authority's first choice is to immediately abandon that leader and all of his forces?
