Both are crime dramas with a focus on psychology and motive. Aku no Hado gets the viewer inside the head of a serial killer while Strawberry Night Saga is from the perspective of a victim turned detective.
Both are crime dramas with the same male lead, although Kamenashi has more to do in Red Eyes, but the premise for Strawberry Night Saga is probably a little deeper overall. Both are decent additions to the crime genre.
