Botched

Now, there's a word I like to see. And there's a lot of it about (botched operations, botched track repairs, botched industial oven maintenance, botched occupation of Iraq...).

Botched evokes just exactly the kind of slapdash, half-hearted, unprofessional behaviour that infects the world; but it also implies the other thing, the thing that makes such behaviour immoral: malice, or prejudice.
