Answer:
He had done most bitter wrong
To some who are near my heart,
Yet I number him in the song;
Step-by-step explanation:
In this excerpt of his poem "Easter, 1916", William B. Yeats mentions the people he knew who were among the revolutionaries in the Easter Rising. The Easter Rising took place in Dublin, Ireland, on Easter Monday in 1916. A group of leaders and revolutionaries occupied government buildings and proclaimed Ireland as a Republic independent from England. Unfortunately, those people ended up being killed.
Yeats mentions, among others, his enemy John MacBride. He talks of John as being a " drunken, vainglorious lout." It is said that, throughout his life, Yeats was in love with the woman MacBride married and, allegedly, physically abused. Even though Yeats has his reasons to hate this man, he numbers (mentions) him in the song. MacBride too fought for independence, and died for doing so. Yeats acknowledges his courage and leaves personal animosity aside to give him the credit he deserves.
