General Order 24 appears to give the captain the right, without consultation, to commit genocide and omnicide.
If there was any proof that GO24 actually exists, other than something Kirk made up on the spot to bullshit the Eminiar war council, I'd be more willing to listen.
To reference another franchise Darth Vader led from the front and would not "order the troops to do something he would not".
True, Vader is often in the thick of it, but I wouldn't take this as any indication that he actually cares about the personnel under his command. Just look at how easy it is for him to force-choke anyone he feels like.
A better example of true "leading from the front" would be somebody like General Veers, who personally led the attack on Hoth from his own AT-AT.
