What a deep word
"When a brother turns a foe,
And an enemy becomes your ally.
This one I won’t let go,
For it’s the last straw, I can’t lie.
A sword put at the heart
Without a rethink of who’s hurt.
For this anger burns the furnace at its hearth".
Just think about the burning feelings of betrayal Ceasar must have gone through that in his desolate state, muttered
" Even you Brutus"
