I really cannot say. I don't think anyone really can. We have to remember the words of the Gospel, "Peter answered and said unto him, Though all men shall be offended because of thee, yet will I never be offended. Jesus said unto him, Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice. Peter said unto him, Though I should die with thee, yet will I not deny thee." (Matt 26:33-35). I would like to say that I will stand firm in the faith and face martyrdom for Christ, but what if I end up denying knowing Christ like St. Peter did? He was so sure of himself that he would die with Christ but he denied him so I can't say for sure.
There is also a story about a delusional monk who walked around thinking he was a saint and was going to die a martyr's death. His abbot seeing this delusion started to beat him and as the monk was being beaten he cried out "Stop! I cannot take it!" The abbot replied, "Whats wrong? You want to be a martyr! I am making you a martyr!" and seeing that he couldn't take the beatings anymore, he repented of his former delusion and lived the rest of his life virtuously.
We can say that we will become a martyr all we want, but what happens when we are face to face with it?
