Has it though? Look at all the major events in the 80s 90s and 00s. The world is pretty normal. People might be more aware of things, but I am betting that feeling is due to 24/7 media and social media shoving high definition images and videos down everyone's throats trying to sell ads with click bait headlines.
Have to agree, look at any part of history and mankind stands out as cruel, misogynistic, hardcore unfair place. People just accepted all this, death and suffering as common part of life.
