Is it ever good to be devoid of emotions?

I wonder if it is a blessing in disguise when you are denied emotional support from people around you because in the end everyone has to find their own way around their problems and one can only gain emotional experience by having to deal with instances first hand.

On the assumption that we all have to learn and acquire emotional competencies through direct experience, we would be independent from the network of support of friends and family and for some people who do not have access to such network anyway, it just makes perfect sense. I just feel sad though that the world would be such a place where only the emotionally strong will get through it and be selected in the natural selection scheme of thing. Vocabulary like compassion will not exist.

On the other hand, it could be argued that everyone can build such a network as long as they are committed to returning the favour. So basically, if you are emotionally available for people around you when they need support, then surely someone would be deemed to be there when you need them. And the concern for one another could be a genuine one even though you are not related as family or even friends, it does not have to be the case of "I'll scratch your back and you scratch mine".

And what is the answer?
