Jung said something like ‘you don’t become enlightened by imagining figures of light, but by making the darkness conscious.’ Maybe your hatred is pointing to something you’ve been avoiding about yourself.
I guess you can, but it would just be you hating yourself. TF journey is not a rosewalk, it will trigger like hell, overcoming all these is a thing… but not based on hate, hate is a low frequency. The aim of TFs is unconditional love 
In the past, when I would get angry with my twin, I would always have a friend who would start talking trash about him & in a snap, I would flip on my friend.
I knew they were just trying to be there for me and be a good friend, but I couldn’t help myself.
