Does the fact that whatever happens to us is a result of our own karma imply that we passively accept whatever happens to us or not bother about the results on others of what we do?

From Ravi:

According to Gita, You get something in response of something you have done. “Jaise karoge, waisa bharoge”. Hence what ever any body is getting, one is getting and other is losing is the response of their past work. This is the way world continues. When ever some one loses, he should analyze what wrong he has done in past and what good he can do.
