If the terms are not unbearable? Yes, unless he liked prison. Him bragging about his hard drives and then after he got a bail are likely because he thought he could get away with it.
If he gets banned from the internet for 1 year or so, I can see him going through it, because not doing so would mean guaranteed return to prison and less time with internet than right now. If however the probation is something completely insane like a lifetime ban on the internet or something like that, then yes, he will definitively violate the terms and/or shoot himself in the head.
Which is why I am asking what is the maximum time he can be put on probation.
