It sounds to me that you did a good and just thing, and that is that,,
we cannot afford to waste time in life situations such as this to argue over a value judgement or three, you gave him food for those fundamental needs,

feel good about it if you can , I know it doesnt sound like my place to say this perhaps, but you seem to have quite a different set of values from your guy? or is he just trying to sound strong viewed?

well, I think that was a really kind thing to do, and it might help the down and out guy to connect, whats a drug anyway, Proxac, Valium,
Alcohol,, etc etc,,

well done for you,, but I respect your guy's own view nonetheless..

you should be feeling good, I am sure you made somebody feel cared about in some way today, that he might never have expected,

take care and best wishes......
