Why do people only seem to care about PED use when it comes to cheating? Gaylord Perry cheated, he's a HOFer!?

There are also stories of Ty Cobb & Tris Speaker 2 Hall Of Famers that may have threw away games but in the case of Cobb he retired from Baseball before the investigation got really strong. Cobb was also suspected of killing someone. But yet these 2 are in the Hall Of Fame.
