Is The Goddess Clan Good Or Evil?

So we've been talking about the Goddess clan for some time ... and weirdly enough some people (like @pandapugger22 and I ) got the vibe that the Goddess clan had a dark side

Remember when they asked Ban to kill Meliodas ?

Spoiler: The Goddess ckan asks Ban to kill Meliodas

That was already fishy enough but there's more...In the last chapter (187) we discovered a part of what they did

Spoiler: Goddess clan deeds

Deceiving people and killing "innocents"

This is not really what you'd expect from this clan ...
So now I'm wondering ...
