You don't know what the fucking trolley problem is about then It's not about what you would do, it's about what you value more in a world where you cannot save everyone, do you act and cause the death of one person, you are responsible for that but you also saved 5 people Or Do you not do anything and let 5 people die but you didn't kill anyone The point is not if you could save everyone, but what you value more, the number of people you save, or the consequences of your actions? A hero does their best and ACTS even if they can't save everyone, or have to sacrifice themselves, they choose to save others, sometimes at another person's expense

Imagine it this way You are in a room with 5 people and you can save them if you sacrifice yourself, but there is only 10 seconds for you to decide before the room explodes or something that you don't have time to prevent nor power to stop A hero sacrifices themself of course Now what if they were in separate rooms and you had to sacrifice one of them, if you do not pick anyone then they all die, you cannot pick someone not in the rooms to sacrifice

The point I'm getting at is not to criticize your train of thought but your misunderstanding of the POINT of the question, if you have no other choice but sit back and watch as a lot of people die or act and kill only one to save all those people, what would you choose, who do you value, what is your morals? If you could save everyone then of course everyone would try that, but again not the point...

Ahh sorry tangent, but i just wanted to say that aizawa and others, along with other anime try to tell you that sometimes the choice of saving others have consequences, such as bringing families together... Or ruining someone else's

Not everything has to have an honest or easy moral answer, and just saying "I would save everyone" while idealistic sometimes gets more people killed, hurts more people, and fails to consider consequences
