Conscience

QUESTION: I would like to ask something about self-responsibility. Would not self-responsibility lead to irresponsibility toward others? If I am responsible for just myself, how then am I my brother’s keeper? Wouldn’t it lead to selfishness, being responsible only for my own life and well-being? I would look for that which is best and most suitable for me first, and only then consider the other person. Although I would give the other equal rights, I would consider myself first.
