ELI5: If your body reacts to certain foods it perceives to be a danger to you for the purpose of keeping you alive, how is it that the allergic reaction itself is so often what kills us anyway? Is it just bad at this?

Essentially yes, it is sometimes bad at this. Allergies are your immune system mistaking something harmless for something dangerous. Your body can then massively overreact to the percieved threat, and do you harm.
