What? So u want a summary of any FBI?
The best answer to this question would be, "Whom would you like to invite to the party?". Whom is an objective pronoun.
Answer:
George's decision to kill Lennie is reminiscent of when Candy's old dog was killed. Whether or not it was justifiable is a matter of opinion, but George's intentions were not doubt pure. George knew that Lennie would no doubt have an awful life even if he wasn't caught, for at that time it was very difficult living with a mental handicap. George wanted Lennie to die while happy.
Wow, that was good. I'd put more rhyming words depending on the poem you want it to be, but all in all great work.
