I let my boss ruin his own sleep schedule for six months to protect a lie

My manager is obsessed with hustle culture. For the past two years, he has made passive-aggressive comments in our weekly meetings about how real leaders wake up before dawn. To prove his point, he sends out detailed project update emails every single weekday at 5:15 am sharp. six months ago I noticed a small typo in one of his drafts during a screen share and realized he had fifteen different emails queued up using the schedule-send button in Gmail. He wasn't waking up at 5:00 am at all. He was writing them during lunch the day before and sleeping until 8:45 am. Instead of calling him out, I started setting an alarm for 5:16 am. Every time his scheduled email landed, I immediately hit reply with an urgent, time-sensitive question that required an immediate decision before 6:00 am, marked "high priority." The first week he ignored them, so I brought it up in the team standup: "Hey, since you're already online and grinding at 5:15 am, why didn't you approve the client file?" To keep up the fake hustle facade, he was FORCED to actually start waking up at 5:00 am every single day just to answer my replies. He looks like a walking corpse now. He is constantly chugging energy drinks and the bags under his eyes look purple. He should of just admitted he was scheduling them. I have zero plans to stop.
