Answer 1

HTML double quotes values. If your values are always going to be "true" or "false" then you can specifically check for "true".
// change your json into an array
$values = json_decode($yourValues, true) ;
// loop through and check for "true"
foreach($values as $key=>$value) {
$values[$key] = ($value == "true") ;
}
// if you need it as json again
$yourValues = json_encode($values) ;

For you case,
#foreach($role->permissions as $key=>$value)
<td>
<input type="hidden" name="permission[{{$key}}]" class="role" value="false" {{ (boolean)$value ? 'checked' : '' }}>
<input type="checkbox" name="permission[{{$key}}]" class="role" value="true" {{ (boolean)$value? 'checked' : '' }}>
</td>
#endforeach
Try like this
####edit####
$data=$_POST[];
foreach($data as $record){
$record=(boolean)$record;
//now $record is boolean
}
