My brother in law said no to having an emergency caesarian and my sister had a stillbirth and nearly died

They just told us that my sister is no longer pregnant and she all but died. She went into labour and the midwife suspected that the baby had died but my brother in law has refused to have her in a hospital. He wanted her to stay in a birthing facility. I don’t know the details but apparently they had to fight for ages to get a transfer to a hospital where they could have a serious procedure done and my sister nearly didn’t make it. The baby had died. I feel sick for my sister and angry at her husband. This never would have happened if he listened to my sister and the people around him. I’m not sure what to do. I just feel so terrible for my sister.
