If a victim of Madoff who was robbed defrauded and swindled would kill Madoff is that justifiable homicide?

whether it would be or not I dont know, but it ought to be

You watch too much CSI Miami! LOL

No, homicide is NEVER justifiable.

BTW, you may get a greater variety of opinions under Society & Culture (or similar topic), rather than under Investing.

You think money is more important than human life?

The crime would be murder, not justifiable homicide, as it should be.

The only time a homicide is ruled justifiable is when in defense of a human life.

Intentional murder is never excused.
