I'm watching a TV programme. There is a line saying
"Everyone loves to think that the doctors can have these almighty powers and heal us and do the right thing by us..."
<< --- first question removed --- >>
Second, what sense of By is used here? Does it mean beside, like sit by someone?

<<< ----------- See Rule#2 ----------- >>>
