In the UK, as suicide is no longer against the law, technically people do not 'commit' suicide - they either 'kill themselves' or (less baldly) 'end their own life'. A 'successful' suicide is termed a completed suicide."to commit suicide" to kill oneself
"to be suicidal" to be in a state of mind where you are contemplating killing yourself
"to go suicidal" I have never heard this term. Where you find it?
As a native speaker it surprises me. It's not idiomatic. I suggest "to become suicidal"Well, 'suicidal' is a state of mind akin to being crazy/mad/mental, etc., so I suppose 'go suicidal' follows the same pattern, as people do 'go crazy/mental/mad, etc.' I had not heard it either, but it does not surprise me.
No longer against the law? That's news to me. What about "assisted suicide"?In the UK, as suicide is no longer against the law, technically people do not 'commit' suicide.
You are right, Edinburgher. I was writing too loosely. It is the attempt at suicide which used to be a criminal offence. Incidentally in the past the corpse could be 'punished' by being buried in 'unhallowed ground'. Of course assisting a suicide is quite another matter and is still (but perhaps not for much longer in all cases) an offence.No longer against the law? That's news to me.

Besides, just because something is not a crime doesn't mean it can't be the object of the verb 'commit'. Committing suicide is still very much in the current vocabulary.
If a suicide is successful, then of course it is impossible to punish the perpetrator-victim (you cannot jail a corpse).
Then there is the old joke about attempted suicide being a capital offence (i.e. a crime for which you could get the death sentence). Who says crime doesn't pay?
To the original question, the answer is no. To commit suicide is to end one's life. To "go suicidal" would mean to enter a frame of mind in which (for whatever reason) one rates one's own life at a lower value than some other objective one wants to achieve. A soldier might be described as heroic when he risks his life to save that of a colleague, but might also be described as suicidal, even though, of course, he doesn't actually want to die in the act. Someone might opt to become a suicide bomber; that could be described as "going suicidal", but here the objective isn't to commit suicide (it's merely an unavoidable side-effect), the aim is to serve a "higher purpose", typically by committing murder at the same time, but other examples of going suicidal might be self-immolation, where there are usually no other victims, and one does it only to make some sort of political statement.
It wouldn't surprise me, either—in the right context, that is. I wouldn't normally expect to hear it in a serious context, though, but I guess it's possible. As wandle points out, it seems too light in tone.Well, 'suicidal' is a state of mind akin to being crazy/mad/mental, etc., so I suppose 'go suicidal' follows the same pattern, as people do 'go crazy/mental/mad, etc.' I had not heard it either, but it does not surprise me.
