riddle - Still going strong - Who am I?

Search, searching, still searching am I,
For those that on that one day did die.

We don't even know the name of the place,
I'm going there, even if you can't keep pace.

In the world out there, some things are pure,
No flowers or vines, but named for sure.
I took it apart, and saved so many lives,
In the fight that left so many husbandless wives.

Most really like me, except when I was given.
Still trying to decide if I've been forgiven.
There was a close call, but it is alright,
Though for a while, I was quite the sight.

Hint 1:

For some direction on how the clues might be organized, see some of my other riddles, such as this, this, or this.

Hint 2:

Each stanza deals with something different.

Hint 3:

"Who" may imply a singular that isn't singular.
