Evil Helps Good

If Evil Helps Good, does that make it less evil?

When an evil force provides a good one assistance in some way. This can be permanent or temporary and can come in many forms. The most common form is if the Bad Guys join the Good Guys because their cause is either a threat that affects many people, including them, or an enemy of theirs who isn't the Good Guys has done something wrong to them (such as kidnap one of their teammates or attack their base) and they figure that the only way to get revenge is by siding with the Good Guys so they can team up on their enemy. A less common reason why Evil Helps Good is because the Good Guys first helped the Bad Guys with some selfless deed which they want to repay the protagonists for.

Note that for this UnTrash to apply to the scene, the Bad Guys must completely have the intention of aiding good, so if they want to trick the Good Guys into thinking they're helping, this UnTrash won't work with that scene.
