Not really, no.
There are people out there that need help- people I like, people I don't like, and people I don't know. My own personal bias isn't an objectively valid reason to determine if someone is or isn't "worth" helping so I ignore my own biases. I'm left with people all around me who need help and me in a position, with the ability/skill set to be able to help them. There's no reason not to make their lives better.
Similarly, I'll from time to time go to the store and buy a ton of flowers and keep them in my car during the day. When I see someone who looks like they're having a bad day, I'll get some and give them to that person.
If I have the capacity to help someone, and there's not a pressing reason not to (personal safety- although I ignore that frequently, someone else needs more urgent help, etc), then why would they not deserve the assistance?
