I wanna point out what I think is an important distinction when it comes to Leoâs self-sacrificial tendencies.
People tend to view self sacrifice as akin to suicidal tendencies, which while can be true, I donât think fits Leo (or any of these characters). Leo has insecurities, yes, but he doesnât view his life as less valuable. I donât think he believes his brothers think that, either, even if he doesnât think they trust him, worries they may not like him sometimes. Leo knows they love him.
Leo understands the strategy of self sacrifice. The only situations heâs willing to throw his life away are when it will save his brothers (and, perhaps ironically, when he believes heâs at fault for the danger theyâre facing). He offers himself up in the maze of death, to Piebald, and to stop the Krang.
This is not because he thinks heâs less than, itâs because losing one of his brothers is his worst fear. He was devastated by Karaiâs death, CJ throwing his families mortality in his face is what gets him to learn a vital lesson.
Leo doesnât want to die. Itâs written in the despair paralyzing him in the prison dimension. âItâs is his last resort because the idea of losing them is scarier than his own death (which also terrifies him). If it means saving them, heâll do it every time.
Every single one of these characters would die if it meant saving each other. None of them want to live in a world where someone is lostâtheyâd rather it be them. Because the most important thing to them is each other.
Itâs not that they view themselves as expendable. Itâs that they value each other more than anything else in the world, even their own beating heart.
When the world is ending and thereâs no other options, he even asks it if his brother, because thereâs a chance they can save the world with the last of his power.
