try and catch clause in laravel controller methods.

Hello everyone. I would like to know if it is necessary to add the try and catch tags in each method of the controller.

I generally use the following line to validate the request data:

 if (Auth::attempt($validated))

But in this case there is no user yet to validate because it is the singup function

public function singup(Request $request)
{

    try {
        $validated = $this->validate($request, [
            'name' => 'required',
            'last_name' => 'required',
            'email' => 'required',
            'password' => 'required',
        ]);

        $user = new User();
        $user->name= $validated['name'];
        $user->last_name= $validated['last_name'];
        $user->email = $validated['email'];

        $user->password = bcrypt($validated['password']);

        $user->save();

        $code = random_int(1000,9999);
   
        Mail::to('[email protected]')
        ->cc('[email protected]')
        ->queue((new EmailConfirmation($user , $code))->from('[email protected]', 'Laravel'));

        return response()->json([
            'status' => true,
            'message' => 'Email sent',
        ], 201);

    } catch (\Throwable $th) {
        return response()->json([
            'status' => false,
            'message' => $th->getMessage()
        ], 500);
    }

}
