I feel I should add, however, that even though I'm glad that Jason Trask is dead (as if he ever existed in the first place - eh :rolleyes: ), it would still have been wrong to kill him just because he was so dangerous. Rachel killed him because she absolutely had to stop him, and it wasn't possible to stop him by any other means than killing him. If she could have stopped him quickly and efficiently without killing him, then she would have been obliged to do so. And then, of course, Jason Trask would have told the whole world about the dangerous alien Clark Kent and the Kryptonite that could kill him. It would have been horrible. Still, allowing Trask to survive to say these things would have been the right thing to do.

But since it wasn't possible to stop him and prevent him from killing others without killing him first, Rachel did the right thing when she shot him dead.
