Consider Aloho as a foil to Ogeyi.
In literature a foil is a character whose qualities contrast with another so as to throw the second character's traits into sharper relief. In Frank Ogodo Ogbeche's Harvest of Corruption, Aloho serves as a foil to Ogeyi, for the two friends respond to the same corrupt society in opposite ways, and Aloho's fall makes Ogeyi's integrity shine the brighter.
Similar beginnings, opposite choices. Both are young, educated women seeking employment and a decent living in a difficult economy. This shared starting point is important, because it shows that the difference between them lies not in circumstance but in character and moral choice.
Aloho's moral weakness. Desperate for a job and dazzled by comfort, Aloho allows herself to be drawn into the corrupt orbit of Chief Ade-Amaka. She compromises her principles, becomes entangled in his web of vice and drug trafficking, suffers pregnancy and abortion, and is finally destroyed. Her tragedy is the direct fruit of yielding to temptation.
Ogeyi's steadfast integrity. Ogeyi, by contrast, refuses to trade her honour for advancement. She warns Aloho against the dangerous path, holds to her values despite hardship, and stands finally on the side of justice. Where Aloho bends, Ogeyi remains upright.
The effect of the contrast. By setting the two side by side, Ogbeche uses Aloho's ruin to measure the value of Ogeyi's constancy. Aloho's downfall is a warning; Ogeyi's survival and vindication are a reward. The foil relationship therefore sharpens the play's moral: corruption destroys those who surrender to it, while integrity, though tested, endures.
In conclusion, Aloho functions effectively as a foil to Ogeyi. Their contrasting responses to the same temptations dramatise the choice between compromise and principle, and Aloho's tragic end gives full weight to Ogeyi's moral triumph.
