Headscratchers / Furious 7

• Is the God's Eye actually more trouble then it was worth for Dom and his team? They went on two highly dangerous missions to pick up Ramsay and her equipment, then the one time they use it, they get sucked into a trap. Given the ease with which Deckard constantly found them, wouldn't they have been better off just setting a trap for him?
• When Mr Nobody is injured why does he entrust Ramsay with Dom and his team. Given she is effectively the only one who could disarm the God's Eye shouldn't she have been rushed off to the nearest military base for safe keeping?
  • It's pretty obvious that Mr. Nobody took a liking to Torreto and wanted him to succeed. I mean, the guy outright says that Deckard wasn't of interest to him, and yet he goes personally to help Dom get him. Clearly, he was aware that without Ramsay they weren't going to make it.
• Why did Ramsey never think to put a failsafe on the God's Eye? A hacker of her level should have been able to come up with some way to prevent its abuse, I mean she made the MacGuffin that can trace and find anyone who has been near a digital recording device within hours, in any modern situation story that is a Story-Breaker Power, was it too much to ask to at least put a password on it?
• Was it responsible for Dom and his team to head back to LA. By setting up the trap there, they were probably responsible for the deaths of several people.
  • They've shown little to no concern for collateral damage in the past. They started out hijacking trucks in the most dangerous way possible and at a minimum could easily have gotten the drivers of those trucks killed. Of course Fast Five brought this to a whole other level.
• Why does Deckard attack the hospital in the opening scene? He's effectively a ghost to the general public so he'd have no problem just walking in and visiting his brother normally. There's a chance his brother wasn't allowed visitors but Deckard could have sneaked in if needed. Most importantly, he threatens the workers there to take care of his brother, yet he just crippled the hospital's ability to do so. The simple explanation of "Deckard wanted to be dramatic / made an irrational decision" doesn't line up with his characterization either.
