Especially since Jesus would equate the donor to "the good Samaritan"
Luk 10:36 Which now of these three, thinkest thou, was neighbour unto him that fell among the thieves?
Luk 10:37 And he said, He that shewed mercy on him. Then said Jesus unto him, Go, and do thou likewise.
Note - Jesus doesn't add, "...except if you are a dirty rotten sinner who proves you're incapable of showing mercy because you send water in a filthy beer can."
