To be fair so does every airline in the world - it is called insurance. If an airline thought it's risk of a hull loss was zero they would save the expense.
Which would be stupid, given that hull losses can happen quite happily without the help of crew, experienced or otherwise (for example - Sri Lankan getting its planes BBQ'ed by the Tamil Tigers, or Malaysian airlines getting shot down by the Russians, or writing off an A330 due to undeclared dangerous goods)
