You can kill Zevlor to help the Druids drive out Tieflings, so Kagha dont kill them, when ritual is completed ...
You can kill Myconid Sovereign, so the other tribe of Myconids can be created there ...
You can also kill old Myconid Sovereign, so the current tribe can live ...
You can poison whole goblin camp (including women, childern and civilians), so you can help Owlbear cub to escape ...


These things are not gray at all, honestly. You kill someone in their own grove so guests/visitors can stay. Pretty evil.
Killing someone just to drive a group of refugees out. Pretty evil.
Killing a creature just so another tribe can settle there. Evil.
Poisoning sentient creatures, including children just so some random wild animal can escape is evil. (The killing in itself isn't neccesarily as goblins are evil creatures themselves. Poisoning might be closest to the morally grey, but the context here and the reason is kind of bad)

I do not know enough about the myconid story to judge on the other thing, context may define that situation better.

Morally gray is not just doing a bad thing for a good cause, that is not how Forgotten Realms work. It may be a thing for anti-heroes, sure. But those are not really morally gray in these situations. Killing people/stuff just to get something done is kind of easily defined as evil
