characterized by injustice or wickedness; wicked; sinful.
Many children may think it iniquitous of adults to force them to attend school, but the adults insist that it does some good in the long run, so the kids have to suck it up and go anyway.
So... that sentence started off dignified, but my bad feelings about being back at school got through and ruined it. For serious, I just do not want to be back at school.
