Knives can kill people. Are the makers of the knives responsible?
How about the marketers?
Let’s assume X out of every 100,000 knives are used to do harm. When they do more effective marketing to sell more knives, does that affect their responsibility?

When you take ownership of your marketing success, do you take ownership of the side effects as well?
