Adam was not born in sin but chose loyalty to his wife rather than trusting God to resolve the trickery. There in he sinned, and took what was forbidden. He chose what we might even (in our sinful flesh) consider the noblest of choices. He chose to die with the one whom he loved rather than choosing the relationship of love with the creator.
Did not Jesus say that unless one hates (a relative term) father, mother, brother, sister...?
Judas of course was born a sinner.
Both became a slave to sin, hiding from God. Judas hiding that which God already knew of him. "Son of perdition (ruin, loss)" the Lord called him.
Christ protected them all except He purposefully did not protect Judas, but such was that the Scriptures were to be fulfilled.
Does not that show the specific and irresistible grace in which one is called, preserved, and presented in comparison to those who are not?
Well, I think that Bundy was born a sinner. Environment is immaterial because Adam was in the Garden of Eden, which was better than this world, when he sinned and Judas Iscariot was right next to God in human flesh when he sinned so everyone is born a sinner.
