Alma 3:19

"Now I would that ye should see that they brought upon themselves the curse; and even so doth every man that is cursed bring upon himself his own condemnation."

We all have agency, which is our ability to make our own choices. Each choice we make has a consequence and we cannot choose our consequences.  If you choose bad things, then you bring upon yourself condemnation.  God does not curse you, but you curse yourself.
