You dont know that. He could seem like the nicest person in the world and you would never think that he would commit suicide. But you dont know what HE thinks.
Yes Heath Ledger died! In January!! You are six months behind! If he did OD, it was accidental. His closest friends and relatives say he had too much going for him and he knew it, and just the type of person he was he'd never take his own life. It had to be accidental.
You cant really say that the OD was accidental but you cant say it was on purpose either.
Whenever Richard Cory went down town,
We people on the pavement looked at him:
He was a gentleman from sole to crown,
Clean favored, and imperially slim.
And he was always quietly arrayed,
And he was always human when he talked;
But still he fluttered pulses when he said,
"Good-morning," and he glittered when he walked.
And he was rich, richer than a king—
And admirably schooled in every grace:
In fine, we thought that he was everything
To make us wish that we were in his place.
So on we worked, and waited for the light,
And went without the meat, and cursed the bread;
And Richard Cory, one calm summer night,
Went home and put a bullet through his head.
