(Batman) What would be different if Batman had no qualms about killing?

Would he become stronger or weaker? What would change in hos arsenal? How would it affect his interactions with other characters? 

I would greatly appreciate any response.

Well his rogues gallery would be a lot smaller for one.

But realistically he would have been stopped a long time ago, likely by another hero. Not killing (excepting the very odd exception) is pretty much one the big separating factors between hero and villain. Even those who still identify as heroes are shunned at best  or actively blocked or shut down, maybe even killed at worst. It's important that they maintain their image as public servants, which is legal, and not build a reputation as vigilantes.
