Ideas of what ethical points the movie makes:
Technology isn't inherently good or bad; it depends on the people who use it and the purpose for which it's used.
Both Jedi and Sith use lightsabers, though one is seen as a means to protect, while the other is seen as a means to destroy
Droids are seen to fulfill multiple tasks, usually for convenience or as a helpful aid; however, near the end, there are droids used by the bad guys for war
In this movie, the clones help save the Jedi, so their creation isn't seen as negatively as the battle droid factory
Large-scale automation can be weaponized.
Both the good and bad guys create an army to help their side in battle. The Jedi have a clone army, and the Sith have a droid army, both used to automate warfare
Over-reliance on computing systems leads to vulnerability.
When files relating to Kamino can't be found in the Jedi database, Obi-Wan is first told that it must not exist if it isn't in their files, instead of questioning if the files were tampered with
In the automated battle droid factory, Padme and Anakin are both in grave danger due to the machines, and there are no safety systems to detect if someone is in danger
The creation of the clones is mainly overlooked by the Senate and Jedi because they need their help in the upcoming war
