You don't understand why people are disliking Goku in this arc even though every action he takes is to sabotage his own universe?
Not sure how 'every' action he took sabotage his own universe. What, did Cali and Kale wipe half of U7 or something? And 17 and 18 were right there when he let them go, yet no one seems to give a shit about them. And did Gohan do more 'sabotage' since he let the weaker members of his universe go and fend for themselves?
I've slowly grown to dislike Goku as Super has gone on but this arc is just insanely bad for his characterisation. I loved Goku in Z and even the new movies. He was my second favourite character but now I'm not remotely excited when he's on screen and I can't roll my eyes hard enough when he does something stupid. This is such a weird feeling.
That's because Goku wasn't a character in Z, he was a plot device. And Goku in Z honestly did more messed up things then Super Goku, but for some reason fans only seems to remember Goku giving Cell a Senzu, which was one of the tamest things he did. You want to talk about sabotage, how about him refusing to fused with Vegeta to kill Kid Buu because it wasn't fair to Buu since he wasn't a fusion anymore, despite Buu murdering his sons and remaining friends.
