Anakin may have a somewhat conflicted reaction. Given his past and the events that unfolded in his life, he might be a bit hesitant to embrace a fanfic about his kids. However, his love for Padme and his children would also make him curious. Padme would approach it with enthusiasm. She would be interested in how the fanfic captured the essence of their family. She might even offer suggestions or corrections if she felt certain aspects were not in line with what she envisioned for their family, all while being very supportive of the creative effort behind the fanfic.
I'm not sure specifically which 'betos killing kids story' you are referring to. There could be many fictional or real - life accounts with a name like that. It might be a local or very specific story.
One possible motive could be Anakin's fall to the dark side. The dark side clouds his judgment and makes him see Obi - Wan as an obstacle to his power. He might believe that by eliminating Obi - Wan, he can fully embrace the dark side and gain more control. Another motive could be jealousy. If Anakin feels that Obi - Wan is always favored or is holding him back in some way, this could fuel his anger and lead to him wanting to kill Obi - Wan. Also, the influence of Palpatine might play a huge role. Palpatine could have manipulated Anakin into believing that Obi - Wan is a threat to the new order he wants to create.
I'm not familiar with a particular 'beto killing kids story'. It might be a very specific incident within a certain community or a false story that has been spread. If it's a real situation, details like the location, the motives, and the background of 'beto' are needed to fully understand what happened.
No, as far as I know, there is no such story that is commonly known. There are many stories out there, but this one doesn't seem to be a mainstream or well - known one. It could be a very local or niche story that only a few people are aware of.
Since I don't know the details of this 'beto killing kids story', I can't say if it has been proven true. In general, any such serious allegation should be thoroughly investigated with reliable evidence.
Since I don't know the details of this story, it's hard to say the motives. It could be due to mental illness, or some personal grudges against the families of the kids. But this is just speculation without more information.
The balance of the Force would be severely disrupted. Obi - Wan was a strong Jedi, and his death would mean the light side lost a great defender. This could allow the dark side to gain more influence, leading to the oppression of many planets and species. For example, Anakin could start imposing Sith rule on various worlds without Obi - Wan to oppose him.
There could be a hermit or an outcast Jedi or Sith on Dathomir. Anakin meeting this character could lead to a great revelation. Maybe this character has been in hiding on Dathomir for years, observing the balance of the Force there, and Anakin's arrival disrupts that balance and forces an interaction that changes Anakin's perspective on many things.
