text_A: On 25 May 1997, Bohumil Šole, a scientist who claimed to have been involved with inventing Semtex, committed suicide at a spa in Jeseník by blowing himself up with explosives. Šole, 63, was being treated there for psychological problems. Chemical residue at the scene revealed that he had indeed used Semtex. Twenty other people were hurt in the explosion, while six were seriously injured. According to the manufacturer, Explosia, he was not a member of the team that developed the explosive in the 1960s.
text_B: Could one draw the conclusion that Bohumil Šole was actually trying to deflect criticism away from Semtex and its manufacturer with his final act, by showing that it is the will to commit harm that causes bombings, not the availability of any specific tool?
NO.
