Eval is bad if you're passing it untrusted input. It can be useful in some situations if you know what you're doing.

As for Bun Shell, it runs what you tell it to, just like a shell script or command line in the terminal. It's similar to running file system functions or spawning child processes. It will let you do some damage, sure, but that's your responsibility, "with great power", etc.
