Hope

You work as a scientist in secret facility by the government. You don't know what drives you to keep this job and continue to work there. You watch every single person being tortured and killed as you can't stand no more but help them

You just need their trust and need them to cooperate with you so you could help them escape. You don't know if it will turn out to be successful or not but you are willing to try. They are just like humans but different
