Based on the story provided, here is the evaluation according to the criteria for Tragedy Degree and Comedy Degree:

**Tragedy Degree**:
- There are very minor tragic elements in the story. Lucas has behavioral issues and is at risk of following a "dark path," which could be seen as a moderate setback. However, there are no profound tragic events or deeply emotional impacts.
- Therefore, based on the given criteria, the story merits a moderate score for its minor emotional setbacks.

**Comedy Degree**:
- The story has some light-hearted and positive elements, especially towards the end where Lucas transforms his life and finds purpose. However, it is more of a feel-good, inspirational story rather than a strongly comedic one. 
- The ending is happy and uplifting but doesn't fit the criteria of a strong comedic aspect filled with humor.

Given these conclusions, here's the scoring in JSON format:

```json
{
  "TragedyDegree": 3,
  "ComedyDegree": 4
}
```

**Explanation**:
