how does shylock's loan to antonio differ from antonio's loan to bassanio ?

Antonio's lone is given out of love. There is no monetary gain in it for Antonio. He does not charge Bassanio interest on the loan and probably does not expect all of it back. Shylock's loan is for profit as well as hate. Shylock wants Antonio, a Christian, to give up a pound of his own flesh should he default on the debt.
