Tigerstar became evil due to a combination of factors, including his ambition for power, a desire for revenge, and a ruthless nature. These traits led him to manipulate others, commit acts of betrayal and violence, and prioritize his own interests over the well-being of his clanmates. Over time, his actions and choices further fueled his descent into darkness and established his reputation as one of the most notorious villains in the warrior cat series.
Numerous things. He killed Redtail and betrayed ThunderClan while trying to kill Bluestar. He killed Brindleface, Gorsepaw, possibly Runningwind, and perhaps others. Once he was dead, he tried to get Brambleclaw and Hawkfrost to take over the lake. Brambleclaw foiled him, but that's not the point. That's just a few of the 'bad' things he did.
No, Lionpaw does not become like Tigerstar. While Lionblaze, as he is later known, does inherit some of Tigerstar's traits due to their blood relation, he ultimately chooses to fight against his dark instincts and becomes a noble and loyal warrior of ThunderClan.
Tigerstar trained Lionblaze in the Dark Forest, manipulating him to become a powerful warrior with dark intentions. Tigerstar exploited Lionblaze's potential and desire for power to further his own evil plans.
Not evil exactly. To be leader of all Clans, but not evil.
No. He was only afraid of Brokenstar and Tigerstar.
He tried, but Lionblaze pretty much killed Tigerstar again. Lionblaze is completely good, and is a better fighter than tigerstar.
Yes. He used to learn from Tigerstar, but then he learned that Tigerstar really was EVIL, so he rejected and fought him. He still visits Lionblaze in his dreams, though.

In the Warriors series, Sasha is not Hawkfrost's mother. Tigerstar is his father, and they communicated through dreams and Firestar's StarClan visit before Hawkfrost's death in the "Power of Three" series. This allowed Tigerstar to influence Hawkfrost's decisions and actions.
