This idea applies not only to anime but also pop media in general. I’m just sort of amused that a modern treatment of this old, old tl;dr is still relatively applicable. I hope you will take this at face value.
A little context: If you’re familiar of the story of Moses and his merry band of Israeli wanderers in the desert, this is the part where ol’ Mo gives them the how-to on war. As in, when the Israeli go to war, they ask themselves some important questions. NLT for flavor and ease of reading:
“When you go out to fight your enemies and you face horses and chariots and an army greater than your own, do not be afraid. The Lord your God, who brought you out of the land of Egypt, is with you! When you prepare for battle, the priest must come forward to speak to the troops. He will say to them, ‘Listen to me, all you men of Israel! Do not be afraid as you go out to fight your enemies today! Do not lose heart or panic or tremble before them. For the Lord your God is going with you! He will fight for you against your enemies, and he will give you victory!’
“Then the officers of the army must address the troops and say, ‘Has anyone here just built a new house but not yet dedicated it? If so, you may go home! You might be killed in the battle, and someone else would dedicate your house. Has anyone here just planted a vineyard but not yet eaten any of its fruit? If so, you may go home! You might die in battle, and someone else would eat the first fruit. Has anyone here just become engaged to a woman but not yet married her? Well, you may go home and get married! You might die in the battle, and someone else would marry her.’
“Then the officers will also say, ‘Is anyone here afraid or worried? If you are, you may go home before you frighten anyone else.’ When the officers have finished speaking to their troops, they will appoint the unit commanders.[“]
See? Even back then they’d know to save your drama for your mama.
