No, Somalis are very qabilist, if they turn each other, what makes you think they will not turn on people who are weaker than them? Cadcads regardless of their wealth, do not have the man power or the numbers to take on the Habr Gidr and other Hawiye clans who out number them 10-1.
It isn't about whether they are deemed worth the protection, its just that in the Somali mindset the only one deemed worth the protection is your clan member. Hence, why stronger your clan, the less likely you will be abused.
Things were so bad during the height of the civil war, you had maternal cousins killing each other just because they were from different clans. Ethnic Somalis were killing each other, who shared the same grandmother!!
If someone can turn on their own flesh and blood and not give them protection due to clan loyalty, what makes you think they will protect cadcads?????
