What makes Candy an ideal partner?

1) An ideal partner in terms of the farm? Candy has money to put up for the purchase of the farm, he can cook, he can help out..... and he's willing to help out it any way he can.

2) George tells Lennie to fight back because Curley isn't going to stop abusing him unless he does. Lennie is taking a beating for no reason.... and George is angry. George has also taken a huge dislike to the "abusive" little man..... Curley.
