Response to Prisoner Swap

It's sad but also nice to hear the families of the two soldiers captured in Lebanon a few years ago have closure now. I would not want to minimize their loss in anyway, but it's scary to think of the implications of our willingness to "do anything" to bring our soldiers bodies back.
I understand that it's a very very good thing for Israeli soldiers to know that they can take the risks they need to knowing the dangers of capture - and knowing how we will do anything to bring them back... However, would it not be better for soldiers to know that the knowledge of their health status and being alive is more important than just their bodies being returned?
Did we not send the message that 1.) If a soldier is captured and killed, it's not a big problem because a dead Israeli soldier can still get imprisoned militants returned alive. 2.) It's okay to mislead and give false hope of captures being alive, because Israel will still give in, in the end - and it validates their reasons to be secretive about crucial information...
Are we not putting the lives of current MIA/POW and future captured soldiers at a higher risk by making the statement that we will give you your captives alive even if ours our dead? Does this not give the militants the idea that it's okay to kill a soldier they've captured because they know we'll give them there prisoners alive anyway? Does our "moral code" not obligate us to think practically and about our long term safety?

Additionally, what kind of people celebrate the release of convicted criminals? If it was one of our soldiers that snuck into an innocent families home in the middle of the night and killed the father in front of their 4 year old daughter, and then smashed the daughters head with a rifle butt - I would expect nothing less than to have him put in our prison if he was returned. In the current situation however, we exchanged such a man for two dead bodies and the enemy state (and government) CELEBRATED his return declaring the day a holiday.

I would never want my dead body to be exchanged for breathing evil men.

The best summary of this unfortunate exchange I found here:
