"I never wanted to see anybody die, but there are a few obituary notices I have read with pleasure" -- Clarence Darrow
Sure, Scalia was a nice guy. Despite being opposed on every issue, he and Justice Ginsberg were close friends. If she thought he was a quality person, I'll trust her judgement.
However, his decisions did grievous harm to the nation and the world. I take pleasure in knowing that many millions of people will no longer be harmed by Scalia's decisions. It's not his death that pleases me, it's that he's no longer capable of harming so many people. I'd have been just as happy if he retired.
While the court is shorthanded, some 5-4 decisions will now go 4-4. Ties mean that the lower court ruling is upheld.
So, for example, the SC was planning to soon hear a case on the Clean Power Act concerning regulation of greenhouse gas emissions, and it was anticipated the SC would overturn it 5-4. That won't happen now. With a 4-4 tie, the new law will be upheld.
