Middos can definitely be changed. Moshe rabbeinu was born with all of the worst middos, and he became the greatest person ever.

Avrohom didn’t take lavan as a son in law. He told eliezer to choose from his family because he knew the superior spiritual DNA that ran through it,from Shem and Ever, etc..one or more parts of that chain might be damaged, but a child from that family will have those good genes, and kf they’re appropriate themselves, like rivka was, then it’s a good shiddich.

Not so with eliezer, who had exceptional middos, and was a self made man… however he still had interior , “arur” spiritual genes. As it happens to be, when eliezer completed his task, chazal say hr became “baruch” like avrohom.
