I felt sorry for Walker. Indeed, sadness can devour a person's mind. Being drowned in sorrow for losing someone important can drive someone out of their sanity.
I just couldn't imagine if I were on the shoe of someone who has witnessed a human transformation to weird creature. I might've been petrified if it were me.
Walker experienced, maybe in disproportionate ways, what many have lived around the world at least once: insanity after systematic injustice. It is something really hard to deal with. It may lead to know dark faces of oneself.
Thanks for stopping by. Much appreciated.
It's a nice experience for me to have read your work.
