I think they teach Hunters that Grimm have no souls so that they wouldn't question the morality of killing them. Sounds like something Ironwood would do, anyway.

I myself don't think the Grimm are soulless since...well...they are alive and concious of their actions. If check out the reactions between the two ursa in Yang's fight, it seems like they are capable of actual thought rather than savage instinct.
