As a cyclist, I've seen more motorists blow through stop signs than other cyclists, and they are the ones who can kill someone.
Cyclists always try to use this defense/whataboutism way too often, without realizing that to a pedestrian, you on your bike are just as deadly as a car. Motorists are at least expected to know the rules of the road, cyclists openly oppose any sort of education and even act offended at the idea that they too should know the rules of the road they're on. As a pedestrian in Toronto, cyclists are my biggest danger, not motorists.
