I already did number 1, 3 and 4. Number 2 would work better with a sims having the compassionate trait instead of the good one, because the good trait has the only effect to make the sim happy if he's around a sim with a positive emotion or sad if around evil sims, the compassionate one really make the said sim tense if he acts bad. Hates children doesn't have much of a power regarding the sim's own children, it only gets harder to build friendship with them since they really love to crush children dreams, the best aspiration to pair to make a challenge out of this would be the one that requires to befriend three children. Unflirty sims are hard to flirt with, but have no real problem to flirt with others, they are mostly hard to romance.
