Oh but you can. The unfortunate thing is that keeping on faking it, while possible, is very hard.
People's ideals generally move into conformity with their actions, not the other way round. That's one of the myriad reasons being a spy sucks. If anyone reading was following the police infiltration of left wing groups scandal in the UK, with added sex and dead babies identities the unit involved had a policy of only using married men after one guy never came back. Probably gone native.
