I just finished the two Equinox episodes and in pt 2 when Voyagers EMH beams back to the ship he just deletes the other EMH, while I was watching I didn't think too much about it but afterwards I got to thinking and realized what a stupid move that was. Having another doctor on the ship or even just as a back up when Voyagers EMH leaves would have been really important and could have been a big deal down the line. All they had to do was rewrite his program and he would have been good as new.
