"Oh, apologies. My name is Exal, and I am an E-rank adventurer," Exal introduces itself while still lost in thought before starting to give a vague explanation of his thoughts.
"Once you are strong, all of your actions carry weight. The weight of all those weaker than you. If, this is hypothetical, one's steps could shatter mountains, every step would be accompanied by an earthquake and countless lost lives. If one is a respected king, expressing dislike about someone could get them killed. This is the weight of one's actions and the consequences. That's one part.
The other is that, as you become strong, you can protect those that are unable to protect themselves. How valuable are those lives? Do they deserve to be protected? Is it my responsibility to protect them if no one else does? Just like gods, that get prayed to, offer protection and blessings?"
