I'm not sure about exact ratios, but in general society appears to agree that collective harm is worse. For example, the UK had 'Pals battalions' in WW1, and stopped when they realised that you could end up with whole villages losing all their young men in a single day. The damage to society from this tactic was too high, even if the camaraderie was short term better and the recruitment statistics were aided. If you wanted to learn more about why society cares more about collective death, I'd advise you start by researching topics like Pals battalions, on which plenty of research has no doubt been done.
