However, there are a couple of key moments that might be leading you to this misconception:
* Cornelius de Witt's death: De Witt, a crucial antagonist in the book, is eventually killed by Alex. The circumstances of his death are quite dramatic and violent, which could be interpreted as eliciting a strong emotional response from Alex, but not necessarily tears.
* Alex's emotional journey: Throughout the story, Alex faces a lot of emotional turmoil, loss, and danger. He struggles with the death of his uncle, the weight of his missions, and the moral dilemmas he encounters. This emotional burden might lead to moments of vulnerability, but the specific instance of watching de Witt with tears in his eyes is not described.
Therefore, it seems likely you might be remembering a different scene or mixing details from various moments in the book. If you could provide more context or a specific passage you're referring to, I might be able to help you understand the situation better.
