An argument =           Set of premises that are said to support a conclusion
Logically valid = the premises logically lead to the conclusion; there’s a chain of reasoning from the premises to the conclusion: IF the premises are or were true, then the conclusion would be true.
Sound argument = (a) logically valid argument with (b) true premises.

What do you mean?
'Right' is ambiguous:
Morally permissible = not wrong = ok to do
Morally obligatory = wrong to NOT do it = gotta do it
