I think any of our action should not be motivated by anger towards someone.
If our motivation is based on compassion etc (Brahamavihara) towards the human, then our action will be wholesome.
There was a western gentleman named Henry Olcott who had similar motivation to you and change the history of Buddhism.
He was the first known Buddhist in the western world!
Please see the link below for the full details. Please also check Anagarika Dharmapala for further inspiration.http://en.wikipedia.org/wiki/Henry_Steel_Olcott
Olcott's main religious interest was Buddhism, and he is commonly known for his work in Sri Lanka. He and Blavatsky arrived in the then capital Colombo on May 16, 1880. Helena Blavatsky and Henry Steele Olcott took Five Precepts at the Wijayananda Viharaya located at Weliwatta in Galle on May 19, 1880. On that day Olcott and Blavatsky were formally acknowledged as Buddhists, although Olcott noted that they had previously declared themselves Buddhists, while still living in America.
During his time in Sri Lanka Olcott strove to revive Buddhism within the region, while compiling the tenets of Buddhism for the education of Westerners. It was during this period that he wrote the Buddhist Catechism (1881), which is still used today.
The Theosophical Society built several Buddhist schools in Ceylon, most notably Ananda College in Colombo, Mahinda College in Galle, Dharmaraja College in Kandy and Maliyadeva College in Kurunegala. Olcott also acted as an adviser to the committee appointed to design a Buddhist flag in 1885. The Buddhist flag designed with the assistance of Olcott was later adopted as a symbol by the World Fellowship of Buddhists andl as the universal flag of all Buddhist traditions.
The effort to revitalize Buddhism within Sri Lanka was successful and influenced many native Buddhist intellectuals. Sri Lanka was dominated by British colonial power and influence at the time, and many Buddhists heard Olcott’s interpretation of the Buddha's message as socially motivating and supportive of efforts to overturn colonialist efforts to ignore Buddhism and Buddhist tradition. As David McMahan wrote, “Henry Steel Olcott saw the Buddha as a figure much like the ideal liberal freethinker – someone full of ‘benevolence,’ ‘gratitude,’ and ‘tolerance,’ who promoted ‘brotherhood among all men’ as well as ‘lessons in manly self-reliance”. His view of Buddha influenced Sri Lankan leaders, such as Anagarika Dharmapala.
Olcott and Anagarika Dharmapala were associates, which reflects both men’s awareness of the divide between East and West—as seen in their presentation of Buddhism to the West. Olcott helped financially support the Buddhist presence at the World Parliament of Religions in Chicago, 1893. The inclusion of Buddhists in the Parliament allowed for the expansion of Buddhism within the West in general and in America specifically, leading to other Buddhist Modernist movements.
