Alma 41:5

the one raised to happiness, according to his desires of happiness; or good, according to his desires of good; and the other to evil, according to his desires of evil; for as he has desired to do evil all the day long, even so shall he have his reward of evil, when the night cometh.

One person is raised to happiness because he wanted to be happy and wanted to be good. The other person gets evil because he wanted evil. If someone wanted to do evil all day long, then when night comes, he will get his reward of evil.

One person is raised to happiness because that’s what they wanted—goodness because they desired good. The other gets evil because they desired evil. If someone spent their whole life wanting to do wrong, they’ll get their reward of evil when the night comes.
