So given relatively constant resistance, voltage is linearly proportional to amperage. Double the volts, double the amps.
The resistance of the human body can vary, for instance, if you're sweating, your resistance drops, therefore the amperage increases. Dry skin has high resistance, so if you stab electrodes through your skin and into your flesh, the low resistance of your mostly salt water body will carry a high amperage. But with all environmental factors being equal, if one person gets zapped by 100V and another person gets zapped by 240V, the person zapped by 240V will have 2.4x the amps running through them, and their day will be roughly 2.4x worse.
In other words, sure, guns don't kill people, bullets kill people. But you'll find that whenever a bullet kills sometime, there was probably a gun involved.
