Answer:
He had done most bitter wrong
To some who are near my heart,

Explanation:
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.
The author of the poem "Easter, 1916", William B. Yeats, in the stanza we are analyzing here, mentions the people he knew who were among the revolutionaries. He mentions even his own enemy, John MacBride, that he describes as a " drunken, vainglorious lout." Throughout his life, Yeats was in love with the woman MacBride married - MacBride was accused of physically abusing her. Yeats has, thus, his reasons to hate this man and yet, as he says in the line, he numbers him in the song. MacBride too fought for independence. He too died for doing so. Yeats acknowledges his bravery for that reason, leaving personal animosity aside.
