Yesterday was really something...getting some insight into how Treem feels about the Wights, the reason behind his burning hatred towards them...I now understand what kind of a person he is.
How we deal with the Wights is an understandably personal matter to him, and it's clearly the matter he's most focused on...that said, he did genuinely seem to want to better the lives of the people in the Sanctuary.
And regardless of whether or not I agree with his plan to kill all the Wights outside the Sanctuary, I can't deny the fact that that'll probably make life in the Sanctuary a lot easier.
Having an ever-present threat like that constantly lurking above our heads, it'll only cause unrest and tension amongst the population. And we're probably way past the point of reconciliation.
