Young Groom Looking Unhappy As He Get Married To A Girl He "Impregnated"

I came across photos of two teenagers undergoing a traditional marriage ceremony.

From the images, it was obvious the girl was pr3gnant. True to the ways of some strict African parents, they insisted the couple get married. 

In their view, since the teens were old enough to engage in adult activities, they should now bear the full responsibilities that come with them.

The young man looked visibly gloomy and unhappy throughout the ceremony. He clearly hadn’t anticipated that his actions would lead to marriage, something he felt he was still too young for.

Is it right fpr the parents to insist the teenagers get married because the girl is pregnant?
