It is a terrible tragedy that many innocent Lebanese were harmed. And I agree with you that responsibility is important. That's why we must make sure Hezbollah is destroyed entirely so it can never hurt people again.

The innocent Lebanese were hurt through a combination of

1) Hezbollah's immoral, aggressive initiation of a war
2) Hezbollah's use of innocent Lebanese, including children, as human shields
3) Hezbollah's intentional tactic of maximising Lebanese casualties

4) Israel's moral, defensive actions that carefully tried to minimize Lebanese casualties

Israel's actions were only necessitated because of Hezbollah's actions, and I'm sure you'll agree that Israel should have defended itself -- it's better that way. So the real problem that caused all this suffering is purely Hezbollah's decision to start the war.

For balance, you may want to consider what the causal lists look like for the innocent Israeli casualties.
