What I'm saying is that JARVIS was made by Stark to be his GOOD assistant and he has a different mind than people like Ultron. JARVIS only knows to be loyal to Stark and everything he SHOULD do is be loyal to him. JARVIS never has to do evil so he doesn't. That's why Vision is good. Ultron was loose, he was just born out of the sceptre and observed humanity's cruelty and decided them to be killed. JARVIS was not meant to do things like that and JARVIS can't turn bad. Ultron is more advanced and free than JARVIS is because he can do what he wants unlike JARVIS who obeys Tony.
