1-Warned mens that Clark knew if he saved Lana, another person would die. So Jonathans death is Clarks fault. Clark was willing to sacrifice a lifesource to save Lana. He is willing to kill. This isn`t Superman or never will be. Thats not what happened in Superman the movie or any incarnation of Superman. Jonathans death was of natural causes in every encarnation. In Superman the movie, Jonathans death triggers Superman sense of responsibility with the world. He feels he wants to do more. 2-Jor-el giving his powers back IN EXCHANGE FOR ANOTHER LIFE SOURCE proves that Jor-el is evil since he is willing to kill someone. In Superman II, Jor-el gives Clarks powers back in exchange for his own life source. THe ultimate sacrfice for the good of mankind. 3- In Smallville, Lana deths is Jor-el`s fault. And although Clarks motives for going back to the past were the same as in Superman the movie(LOVE), the results of his actions wasnt.In Superman the movie, in the end, Lois died of natural causes(not because of Clark having his powers back) and Superman altered the course of history by traveling the speed of light to save Lois because of Love. Conclusion: Smallville is a ****ty show with poorly-written characters, that does`nt respect Superman as a character and his integrity, ecxept for some rare episodes like Rosetta. Hopefully Superman Returns will bring back the integrity of Superman in 2 hours since Smallville writers can`t do it every week.
