The only information that I have is, we went to a doctor  and he told us that Tony had a very severe depression and I realised that this led to his mental disturbance.  He really cared for his family and it's members, after hearing about Moosa's death he may have thought that he'd never see the members of his family again and this might have worried him a lot. To be away form home as well might have contributed to this mentally disturbed state.
