There are many types of heros, some may be the best which make them heroric and some heros makes decisons that causes them to fall. These heros are called "fallen heros", in Star Wars Revenge of the Sith Anakin Skywalker makes some conscious decisions that makes him lead into the the evil character Darth Vader. Certain points in the movie helps make the viewers see and could predict where Anakin would fall in early in the movie, by being confused at times, making decisions that could change his future with the jedi.
When Anakin was enlightened with the fantastic news Padme told him, Anakin begins to fall in love with her more than ever! They start to plan what they want to do once the baby was born. But after hearing the news most of Anakins nights were filled with nightmares of his beautiful wife dieing during their childs birth. He worries because the pervious experience with nightmares and death usually happens in reality, he doesn't want the same outcome to happen again just like his mother. So Darth Sidious introduces and tries to influence him into joining the dark side to help Padme live during the delivery.
In Anakin's mind after he figures out his wife could be saved only if he joins the dark side, he thinks hard about it. Since the baby and his wife are his main priorities he makes fatal choices that determines which side hes going to join. For example when Mace Windu attempts to arrest Darth Sidiuos he specifically told Anakin to stay in the Council Chamber and if he told the truth about Darth Sidous being the leader of the siths he earns his respect. Yet after being told to stay he doesnt listen and continues to follow him. Once Mace has Darth Sidious pinned and ready to kill him Anakin makes the quick decisive move and cuts off Mace's hand off, which gives Darth Sidious enough time to counter and strike back and kill him. Anakin is shocked in what he just did and finally bows down and decides to join the dark side.
If Anakin never followed Mace, he would've gotten the respcct and possibly became a leader. But making a couple of costly decsions ruins his shot at being one. His over wanting of power caused him to fall because he let his feelings take control of his mind and it does him no good. Anakin had all the respect by Obi-Wan but since he decided to join the dark side he fought his master and also losses everything.
In conclusion, if Anakin was to follow the rules that were given to him just be faithful, him becoming the Darth Vader wouldnt have had to happen, Padme dieing, and losing the respect from all the Jedi's. All becuase he wanted more power and to rescue his wife. All this isn't worth it, he could've been there with his wife while she was giving birth, possibly being the leader and being recgonized as the chosen one.
