Yurgir may not be the most unambiguously good character in Baldur's Gate 3, but the choice over whether to kill him can still cause internal conflict. Almost every choice matters in Baldur's Gate 3, from the most minor selection of wording to decisions between life or death. To make matters more complicated, every single decision has some kind of consequence, and it's often the most minor ones that come back to bite the party later in the campaign.
