That is your mis-interpretation.
"Hebrews 2:9-10" does not state that all men whom Lord Jesus was crucified for are the sons of God; rather, you are trying to put the two sentences together as if they were referring to the same thing. But by your error you are rejecting all the other Scriptures that state that Lord Jesus died for the sins of the world.
Lord Jesus tasted death for every man, but only those who believe are sons of God - these are the ones brought to glory. That is all that "Hebrews 2:9-10" is stating. But by your mis-interpretation, you are objecting to the Gospel.
John 3:16-18 (WEB) 16 For God so loved the world, that he gave his one and only Son, that whoever believes (continuous believing) in him should not perish, but have eternal life [rebirth of the indwelling Spirit: John 7:37-39]. 17 For God didn’t send his Son into the world to judge the world, but that the world should be saved through him. 18 He who believes (continuous believing) in him is not judged. He who {{{doesn’t believe}}} has been judged already, because he has not believed in the name of the one and only Son of God.
John 12:47 (WEB) 47 If anyone listens to my sayings, and doesn’t believe, I don’t judge him. For I came not to judge the world, but to save the world.
