I think it’s for control and power. If he couldn’t have her, it’s better that she’s dead and gains a sense of superiority from the unreciprocated feelings. To him its power, if it was love he would’ve commemorated her and put her in high regard. But he objectified and put her in a pedestal and took the final control of her life.
