I'm going to ignore a beggar
Why? Is it because you don't care for that person's needs?
Yes, he is not worth any cent.
I see how you feel, but you should help those in need. Consider giving him just a little if you can. He will definitely appreciate it.
Nah, screw that guy! He doesn't deserve my help.
How do you know if he deserves the help or not?  Do you even know the guy?  You shouldn't judge people until you've walked a mile in their shoes!
