If the options are "I die, my pets die, my entire family dies, a slow painful climate and pollution-driven death"
Vs
"these 20 companies get permanently shut down, their resources reallocated, their infrastructure dismantled and repurposed, their employees find new jobs potentially repurposong said industry, and executives get locked in solitary for the rest of their lives"
I know which I'd pick.
And if it's legal to use lethal force when defending one's life and one's family, then it's legal to use lethal force to defend one's life and family
Companies can die without a single real human being hurt.
