When you are so mad at someone that you make a bad decision, even though you will be harmed by it as well, in order to harm that person; is there a good term for this?
For example burning $100 because he owns $20 of it.

"Cutting off your nose to spite your face" comes close to what you are describing.
For a single word, you can consider spite, which means to go out of one's way to harm another for a perceived wrong.
In other words, it means to do something unnecessary (which means there is a cost) to harm another for what may be no legitimate reason at all.
An example is the spite fence. This is a fence that is put up for no other reason than to annoy a neighbor. It is generally done so at some cost to the one putting it up (for the material or at least the for labor).
A Pyrrhic victory. The Greek King Pyrrhus was ruined beating the Romans.
If spite is not quite a good fit, then I would say "collateral damage".
This is when you inflict harm upon yourself in the attempt to attack your enemy.
