This now makes more sense. The headline did a shitty job

Omg thank you for the explanation I was real worried there for a second

Thank you I was very confused seeing many of these countries "against"

Yes I checked my own country (Denmark) and that is green, and for Denmark it is decidedly illegal to vote for death penalty.
So the vote was probably about making death penalty illegal.

PS:
AFAIK it would be against the Eu treaty to vote for death penalty for ALL EU countries.

Yeah I came here to ask about this, because Brazil voting in favor of the death penalty when it doesn't have it did set off some alarms for me

The only people who were confused are the ones who didn't actually read the diagram.
