Besides that, turning it into smaller rocks blasting in every direction would make it more dangerous. Good job.
No it wouldn't. The shower of smaller fragments would have considerably greater surface area, allowing for both more complete burnup in the atmosphere (less mass reaches the ground) and lower impact velocity for those fragments that DO reach the ground. It would be slightly more dangerous to orbiting spacecraft and satellites, but considerably less so for anyone on the ground.
You're turning an asteroid that definitely won't hit Earth into a gazillion of smaller ones that will hit Earth.
