Treachery prevents victim's defensive, retaliatory acts

For treachery to be present, two conditions must concur: (a) the employment of means of execution which would insure the safety of the offender from defensive and retaliatory acts of the victim, giving the victim no opportunity to defend himself; and (b) the means, method and manner of execution were deliberately and consciously adopted by the offender.
