Am I a bad person?

Some dude I've never talked to before sends me a message giving hints that he wants to off load whatever is bothering him and I made it clear I'm not interested. The problem is I changed my mind after a few minutes and when I went to tell him this I found that he'd blocked me. The last time someone came to me with their problems and I gave them advice they didn't appreciate it so I told myself I wouldn't entertain anymore random messages from people.
