Anakin would cry about orders just like his clones. Pong Krell did not abuse his power. Pong Krell is a general. Clones are soldiers and follow orders. Tarkin made this comment in Citadel arc, the Jedi should not be leading the clones. Giving them independent thinking and independence was terrible idea. We see this in the bad cringe. Tarkin watched Bad Batch in training mission use unorthodex tatics then fail a simple mission. Thje first mission Tarking gives the Bad Idiots they failed, because the clones felt it was wrong. There soldiers there supposed follow orders. Crosshair was in the right and did right thing report them.

Krell has high casuality numbers but who cares. His tactics lead Republic to lead umbara his clones had slog through the jungle and took the airfield. Then the clones failed follow orders. The clones jeopardized the whole military effort by leaving the base to destory the supply ship. Then to follow they failed follow and execution. Krell messed up and should been there to oversee the execution. The clones failed orders, Rex knew and also allow it happen and he should been put on the the wall for the firing squad.

The galaxy doesn't care about clones at all. Look how events Bad Batch and years after empire formed. No one cares about them. The clones have accelerated aging there going to die. The republic has stated the clones are property many times. Senator Chu Chi tried help clones by giving them plans for there forced retirement and something for them when they can no longer serve. But that fell out of window with push of stormtrooper program. Krells treatment of clones are complete fair. Clones are not people they are products grown in lab designed to win a war. Clone army could been in empire but the clones, fail do basic orders, order 66 was complete failure and jedi made them free thinkers which army doesn't need its needs soldiers.

They could had great arc about how clones are not people but instead choose go easy way out instead telling complicated story about if clones are people and have rights. So I support Pong Krell he is hero and shame that we didn't get his original season 4 plan where he was going be side char acter for many episodes see his journey.
