Should Nintendo develop more "Mature" rated games?

[F0X]

The first post asked if Nintendo should produce more games with a "mature story", but the title asks if Nintendo should develop more "Mature rated" games.
To answer the first post, I say that Nintendo produces plenty of games with stories that adults can appreciate, so there's not a need to make games with stories that are targeted solely at adult audiences.
To answer the title, no. I don't want to see Nintendo crowd out third-party developers any further by invading the M-rated market. And E-rated games still somehow sell more.
