Is suicide wrong?

[Silver]

But suicide isn't always a personal case, for example suicide bombers, the 9 11 hijackers and so on.

Except the family of the suicide bombers, etc, are proud of what was accomplished. They do not mourn the loss of their loved ones.

The suicide bombers did cause direct harm to others, which makes their actions morally reprehensible. Their suicide alone, however, is not morally wrong.
