I'm looking for a noun that means something dangerous, but it is still a necessary danger so you keep using it anyway.
Examples:
- A power-tool might be necessary for a mechanic, even though it could kill them.
- Someone who is on powerful drugs might regret having to take them, but still take them, as the risk of addiction is better than the immense pain.
Sentence: "I don't want to use it, but the ___ might be our only/best option."
