Agreed, if you already know the person has bad habits, then definitely don’t support those habits.
But hey, occasional help with the basics never hurts. Everyone needs food and water occasionally at bare minimum, plus many people forget they also need occasional help with hygiene.
It’s not like they want to be dirty, they just don’t tend to have regular access to facilities to bathe, shave, or wash their clothes…
But yeah, I ain’t about to just hand them money. If I’m gonna help, I’m gonna help. I can’t do much, but I do what I can when I feel I should.
