I don't think every living creature at the school could see souls, because it's not common. I talked with Katherine, and really, me and another person can do it. As in the anime too, only Maka and Professor Stein could do it.

Ah, I thought soul perception was something that most - if not all - meisters should have. At the very least, I thought it would be something they developed and should have by the time they graduate. 

But if that's the case, then go ahead. Catherine still has soul protect on but it should be noted that seeing through it is literally her final exam for her Soul Studies class.
