Your right, my favorite part really was Harry Kim getting blown up! However, I was sad when he got sent back with the baby...why couldn't they just let him die??
I remember reading somewhere that this was the actual plan, but Garret Wang had certain reservations about, well, not being employed any more, I suppose.
Since they never really developed his character anyway, killing him off here wouldn't have changed much going forward. Although I do wonder if having that extra slot open would've allowed for both Kes and
Seven of Nine later on...
