The curse should fall upon them

2. Alma 3: 18
     18 Now the Amlicites knew not that they were fulfilling the words of God when they began to mark themselves in their foreheads; nevertheless they had come out in open rebellion against God; therefore it was expedient that the curse should fall upon them.
3. Alma 17: 15
     15 Thus they were a very indolent people, many of whom did worship idols, and the curse of God had fallen upon them because of the traditions of their fathers; notwithstanding the promises of the Lord were extended unto them on the conditions of repentance.
