I do quick browses at r/watchpeopledie, subbed an all, but it's out of morbid curiosity and as a learning tool about mortality and accidents. Doesn't affect my daily life, mental state, but does satiate a curious mind.
In my perspective, it's not inherently this corrupting field that causes people to be sociopaths. I don't believe the people on it are morally detached either. In the perspective of a website though, maintaining and hosting the content in that subreddit does raise eyebrows.
I'd understand the reason behind the removal of the subreddit, but it would open a pandora's box of what's truly 'allowed' on reddit.
