You shouldn't have both unimpeded Flurry and Full BAB at 1st level. You should put it back to -2 til level 5, then -1 til level 9. Two attacks at the highest attack bonus with no penalty at first level is just insane.
The very nature of an angel is an artificial being. An angel is not 'born', he is 'created'. And because the angel is 'created', it follows that he has a 'purpose'. He has a 'reason to exist'. Therefore, if an angel suffers, there is a reason for his suffering.
