Blood is expensive.

Kidneys are expensive.

Hearts are expensive.

Hell, even hair can be valuable.

So despite the deaths that you have caused, you feel worse that you managed to ruin a lot of good money that could have helped others. Honestly, you feel real bad about that. Can't do much with flat body parts.

[Your blood constantly drains but you feel compelled to keep it from going to waste so you must find a container to contain it.]
