Yeah... exactly. If seeing family killed makes vigilante heroes inevitable... Statistically there should be a LOT more bat family!
What 10? Since bruce was 8 years old?? Gotham should look like marvel manhatten.
If we took the statistics of one of the most violent cities in America...
And give it the population of New York, to make it about the same size as Gotham... about 8 million...
That would be... about... 4,000 murders per year.
If Bruce is in his 30s..., let's say 35... that means there's been about 108,000 murders since his parents were killed.
If a quarter of those murders had children... and removing 20 years of data to account for possible aging of those children into adults... there could be 15,000 vigilantes in Gotham.
4,000x15 years=60,000
60,000/4=15,000

Because Bruce Wayne is a type A personality who likes to fix things...or at least won't stop until justice is achieved. Or to be crude Bruce can't live with being a victim and he feels that's what happened when his parents were murdered.
Whereas Barry is more of a c'est la vie type of guy. Remember with the retcon Barry was more interested in exonerating his dad than finding out who killed his mother. But honestly it's all just lazy writing by Johns who decided that the only way for a super hero to be interesting is to copy Batman's background.
