AC above 100 Volts kills quickly too. It can actually kill more easily. You need about 4 times as much DC current going through the body compared to AC. 220Volt DC is safer than 220Volt AC. This is in part because our body (specifically the heart) can handle a constant voltage shock much better than a constant frequency interfering with the nervous system. When you get hit with DC, all your muscles contract once, then adapt. When you get hit with AC, all your muscles contract 50 times a second. In fact the IEEE did experiments, concluding that it's easier to let go of a possibly lethal DC source than an AC source for this reason. Additionally, the human body has a higher impedance to DC than to low frequency AC. So you already need more DC voltage to induce the same current.
