First in Kirstoff he seems to be feeding off memories that only demons feed on like envy, desire, rage etc. Justice isn't evil. His inability to exact justice and inside Anders with Anders anger at his particular person injustice, he's gone ape ****. The reason he doesn't look like other abominations(though seems as some can hide it) his because of the nature of the Justice isn't evil and he's not fully possessing Anders, just co-habituating.
The questions I have are this though. Why does a demon need humans so badly? Seems that it's easy for non-possessed humans to summon demons. Since every possessed or blood mage has an army of shades and demons.
Demons feed on humans emotion. If you did Sebastian's act 2 quest, you meet a desire demon that's been feeding on Lady Harimann for quite a while. Similarly, I remember another desire demon in DA:O's mage tower that had latched on to a templar, and wanted to be left alone because she had attached to him and wanted to continue feeding on him.
I'm honestly not sure Justice is as benevolent as Anders makes him out to be.
But why not summon good spirits in turn for good mages?
As Merrill said: There's no such thing as a good spirit. There never was.
All spirits are dangerous. I understood that. I'm sorry that you didn't.
Also: Spirits differ from each other, just as you and Hawke and Isabela are all human.
