ELI5: What is it about electricity that kills you?
gpt
It can kill you in two ways.

The first way is burning you. In general, current generates heat. If there is enough current going through your body, your body will literally heat up and you will burn to death.

The second way - if there isn't enough current to burn you - is the electricity just interfering with your body signals. You brain uses electricity to tell your muscles what to do. Your nerves are basically just biological wires in your body; if you apply a current to muscle it will contract. 

Specifically, the electricity can interfere with your heartbeat and trigger erratic spasms of your heart. This is called fibrillation, and can often be corrected with a defibrillator. If there isn't a defibrillator nearby, well, you're probably gonna die.
