People like doctors or firefighters are multipliers, that is, they make the whole group stronger by a disproportional amount. A doctor can aid themselves and others with above average effectiveness. The same applies to firefighters. A professional firefighter is far more effective in putting out fires, removing debris, and saving people than an untrained civilian. Rationally it makes perfect sense to prioritize them in targeting, as Russians have done. By shooting at field hospitals or doing double-tap missile attacks on cities (first hit a crowded shopping center, and then send another missile 30 min later to hit first responders), you can murder doctors, paramedics and firefighters and harm the whole group by a disproportional amount. Such perfect rationality combined with utter lack of humanity is why most people would call it pure evil.
