I really don't feel like helping.
Why wouldn't you want to help?
Because help is always a burden
I understand it can be inconvenient.  However, you should help others in need.  You may need their help someday in return!
Not if I let them die!
That's a very morbid way to think about it. Think of how upset you would be if you are in need of help but no one was there to help you out. I think this may change your mind on.
