In Baldur's Gate 3, you can kill Aster or not. Players can choose according to their own situation, because whether they kill or not will not affect the subsequent plot.
Answer: It’s okay to kill or not.
In the game, it is okay to kill or not kill Aster, and it will not affect the subsequent plot.
When giving eggs to Esteyan, the player can choose to give them to him, and when he gets them, he will give the player the corresponding reward.
But this reward is only more than 200 gold, and the player can also steal the gold coins in front of him through stealing.
Because there is a plot in the follow-up, if the player kills her, the subsequent plot will be reduced to a certain extent.
