The tordando scene is about Jonathan Kent protecting his Son from the world. It's not about his power or abilities. Clark moments before was complaining and said "You're not my Dad!"
The scene where Jonathan is revealing how they found him Clark just wants to keep pretending he's their Son. He just wants to fit in and be normal.
The scene where Clark is being bullied and the Jonathan asks him "did they hurt you?" and Clark says "You know they can't" which Johnathan responds with "That's not what I meant. I meant are you alright?" Because he's worried about him from an emotional point of view.
When Clark asks "What was I supposed to do, just let them die?" Jonathan says "There's more at stake than just our lives, or the lives around us." He's saying this because Clarks existence is world changing and also he's very reluctant on anyone finding out about his Son.
Man of Steel and Batman V Superman heavily revolve around this topic.How would the world react, what should he do or not do, the controversey if he's a hero or does he bring death and destruction.
Jor EL tells Zod "he will be free to choose his own destiny. Jonathan says "You have decide what kind of man you want to be, Clark, good character or bad, he's going to change the world". This all leads up to the Justice League and Darkside future of him being good or evil because he's capable of both.
