When Gold stabbed Pan, he was holding Pan in a hug, and stabbing him in the back, towards himself. And the blade on the DO dagger is probably somewhere between 18 and 24 inches in length, more than long enough to completely pass through one body and enter the other. (of course, how did Gold have the wherewithall to twist the dagger to kill his dad and himself. The combination of Pain and Blood loss from the initial thrust should have put both men out of commission. But that's probably just a case of needing to just suspend reality for the moment.

With Zelena, it was more of a thrust, away from his body, just like you would normally stab anything (or if you're sword fighting, it would be a natural thrust). in that case, the blade got nowhere near his body, so there is no reason for him to suffer adverse effects (at least not from the stabbing, I think Belle may have some adverse effects waiting for him when she finds out)
