It's interesting that the words for goodness and correctness are to do with the right side:

"The right hand"
"You are right" (correct, accurate)
"I know my rights" (entitlements, privileges)
"Go right on" (straight, true path)
"right in the head" (well, healthy)
"to right a wrong" (redress)
"He's very dextrous" (skilful - from Latin "Dexter")

and, of course, sinister is "all wrong"

It's similar in French:

"le main droit"
"Je sais mes droits"
"allez tout droit", etc.

It's worthy of note, though, that if you add "ni" to "sister" you get "sinister"
