From the Puranas we infer how cruel deamons like Hiranyakashipu, Hiranyakshan etc. were. Recent history portrays the malicious deeds of so many evil-minded people which have caused destruction to humanity. To me, it seems that these modern demons are far more powerful than the Puranic demons, simply because the latter gained destructive powers by staunch penance whilethe modern demons have acquired negative powers sans any penance!
