Treason

Treason for giving aide to enemies of the USA both foreign and domestic is punishable by death, prison and fines.

Is execution a deterrent to treason?
What Treasonous activities deserve death?
What Treasonous activities if I did would I consider my life forfeit?
If my life would be forfeit does that mean the same for family participants?

Even after a life working protecting the USA these questions are still hard for me to answer.
However when treason is obvious I will not be a friend of treason and deny it has occurred
