When is it the right tool?
When you're using it to convert ebcdic to ascii, while swapping bytes
and reblocking an ancient file from a barely readable archival tape.
When is it not?
When copying a file.

Yes: 1. dd will not accept a block size of 0, never mind a negative
block size. You can try it yourself:
$ dd if=/dev/zero of=/tmp/1zerobyte bs=1 count=1
1+0 records in
1+0 records out
1 byte copied, 0.00
