If NYC, or parts of it, are an urban "hellscape" this year, then it was an apocalyptic nightmare every single year between 1970 and 2000.
Every time there's a year over year increase in murders in this city or that, the political right tries make a huge deal out of it. You might want to look at the historical murder rate in NYC. There were 8x the number of murders in 1990 as there have been so far this year. Similar for 1991, 1992, etc. 2245 murders in 1990 vs. 311 in 2019.

Violent crime has plummeted these past 30 years across the country. I can guaranty you that by year's end total murder in NYC will be less than 80% of the years between 1990 and now. The idea that a single year over year spike is anything other than statistical noise is a lie of Trump and the political right meant to dupe people who are too lazy or dumb to look at historical data.
You are either an active supporter of this lie or a useful idiot.
