Coffee has been around for thousands of years but I'm pretty sure %100 pure caffeine could kill if you ingested enough at once
It's not the purity, it's the dose, like any chemical the dose makes the poison.
The FDA recommends staying under 5 cups (400 mg) a day to avoid negative effects with an average person.
It says toxic effects can be observed with rapid consumption of 12 cups, or 0.15 tablespoons of pure caffeine. https://www.fda.gov/consumers/consumer-updates/spilling-beans-how-much-caffeine-too-much
This mystery can be resolved by googling 'ld50 caffeine.' ~750mg is toxic and 10,000mg can kill people
Same as cocaine
Yes, caffeine can kill. https://www.livescience.com/caffeine-overdose-200-cups-of-coffee
