When was the last time a system remotely this bad was actually redeemed slowly? The Mongols were defeated by disease, storms, and violence; the Nazis were defeated by extreme violence; the Japanese Empire was defeated by extreme violence; the French monarchy and Napoleon were defeated by extreme violence; the Russian monarchy was defeated by extreme violence.
Things get worse before they get better with a revolution, but they can get better. That isn't to say that we should decline to reduce harm inside the current system, but it seems naive to expect the current system to stop being terrible. Harm reduction is a temporary measure.
