Blood oath 

Traditionally a blood oath was when one would shed their own blood(Cut yourself or something) and offer it onto a altar or whatever they believed right(sometimes a religious action) and swore to uphold a certain task, no matter what. Also it was when a person(s) would shed blood, usually they'd cut their hand and then shake hands in agreement to a task they swear to uphold.

More modernly it just means you swear to do something no matter what, and since it's a blood oath, modernly it means hurting or even killing others in oath, thus 'blood' oath, meaning blood would be shed in promise to the task, usually a phrase only used by mobsters and crooks.

The great samuraiKenji Setsuna bowed before the altar and cut his hand, offering blood, swearing to protect his people under any condition in belief before his God.
