Bakit paminsan unfair si Lord??

My mom told me na namatay daw Yung anak na lalaki ng bantay namin. For context, I know the kid and my parents are really fond of him. He is jolly and smart, one you could compare to a sunshine. I just find it unfair how his life ends at five. He's a kid born in a poor family, in a third class province, with crappy healthcare, why give him an illness that's just impossible for him to fight in his circumstance? WHY DO THAT TO A CHILD? Sabi ng Kapatid ko pagnakapag tapos siya pag-aaralin niya sana yung bata, same as me kasi I really liked that kid and his fun personality. With the right support, he might have gotten far in life. Sayang lang.
