The earlier stages of the New 52 drastically reduced the Batfamily and we still got an abusive Batman, one arguably worse than anything that had come before (well except for Miller's ASBAR). Look at what he did to Dick after Forever Evil where Dick had been tortured, unmasked and nearly killed on live television. He fakes Dick's death without even consulting him and then verbally and physically beats him down for getting his identity exposed forcing him to go undercover.
The wider Batfamily gets blamed for Bruce's character derailment into an abusive control freak but most of his vile moments have nothing to do with them and the biggest victim of Bruce's cruelty is Dick, the original Robin. Reducing or removing the Bat family won't make Bruce a better person. The writers will just have him be an ******* to other people. Hell, I'd make the argument he's treated the JL members worse than most of his kids so why aren't we seeing more calls for him to be removed from the League?
