You argued that the US intervening more heavily in Syria would have prevented all of the human suffering. I'm pointing out to you that the US' other interventions in the Middle East show that the opposite is likely the case.
Just imagine the chaos in Syria if the Sunni extremist groups that the US supported had won. How would the various religious minorities, like the Shiites, Alawites and Christians, have fared? What's the chance that the Sunni extremists would have carried out genocide against religious minorities? It's one thing to say that Assad is a tyrant, but another to say that everything would be better if the US toppled him.
In Iraq, supporters of a US invasion made the exact same argument. "Saddam is a tyrant? Why don't you want to get rid of him?" The US toppled him, and half a million people died as a result.
Your analysis - everything will be better if the US topples tyrants (and realistically, empowers people who might be even worse) - is very simplistic, and has a terrible track record in the real world.
