Up / Yes: Keep the image, unless a better suggestion is put forward.

• It is a powerful image.
• It illustrates the trope: "no happy endings for gay characters".
• With context, it alludes to the fact that the trope is old-fashioned / discredited: it is from a 1940s flashback. (The article also condemns homophobia.)

Down / No: Delete the image, it is "illustrative, but squicky".

• Gory: The image depicts realistic corpses and blood.
• May be interpreted as advocating hate speech and violence.
• Being an image for a Death Trope does not earn it specialized criteria for appropriateness.
