The Avengers bloody rampages

That's actually a large number considering that the Chitauri had no superpowers and all that was needed to defeat the entire Chitauri army was 1 nuclear missile. If the Avengers had done their job properly, then there shouldn't have been any battle or any casualties. So a thousand dead from the Battle of New York when there shouldn't have been any human casualties makes that a really large number of unnecessary human casualties.
