When Blizzard says Morally Grey they just wanna get you intrigued in the story and to later lowkick you with a cop out that's just not even grey...
Sylvanas is morally grey, it's not that simple, just wait and see. 9 Months later she burns down the tree because a random Night elf made her tell her backstory.
church hurt is where you experience a degree of distance, pain, or judgement from your church community. Essentially, you are just unable to “find your place”. This is prevalent in the Christian community, but can be extended to other religions.
Now that I am an adult I am beginning to heal from the church hurt that was inflicted on me as a child.
